Start gridcoin with a -salvagewallet command, using the backup wallet. Ok, I used the backup wallet I had made from a few days ago, it syncs up to block 40319 then I get "system error:CDB():can't open database file wallet.dat, error -30974" and then it crashes and I get "A fatal error has occured. Gridcoin can no longer continue safely and will quit.
EXCEPTION: St13 runtime_error
CDB():can't open database file wallet.dat, error -30974
c:\Program Files (x86)\Gridcoin\gridcoin-qt.exe in Runaway exception"
I was doing a resync and an update a few days back and got these same error messages. I then restarted the client and they went away so I wrote it off as a fluke. I think a fresh install and new wallet would be in order, I would love to recover those 6K though.
Qt just freezes and shuts down Didn't you say you had an older back-up of your wallet...? Use another back-up, it doesn't matter when the back-up is from as long as it is for the same wallet. All the information for every wallet is stored in the blockchain and when you sync, if those coins SHOULD be there, they WILL be there... |

Re-try launching with that wallet but use the "-salvagewallet" flag on launch... ***Edit*** I see this has been covered already... man, I am slacking today... |

Another question. Do i have to check the box "Use GPU while computer in use" in the BOINC manager? Or does the mining module on the qt client do all the work?
You do not want to have the box for "Use GPU While Computer is in Use" checked. The way Gridcoin works is you dedicate your CPU cycles to BOINC and you mine Gridcoins with your GPU. Gridcoin also has it's own version of cpu mining which should be re-implemented soon (hopefully). When cpu mining is brought back you will be able to fill in some information on your projects console and you will be rewarded additional GRC based on the amount of work your cpu does for BOINC. So basically i am not dedicating any GPU power towards BOINC. Only my cpu is contributing to BOINC projects?? If that's the case then this coin is not energy efficient at all, its just forcing you to use your cpu for boinc while wasting gpu power on gridcoins, i could be dedicating gpu and cpu power to boinc instead of mining for gridcoins. The idea behind the coin is to add an incentive for using BOINC, a handful of people dedicating their GPU's to BOINC is nowhere near as effective as a large network of cpu's dedicating their cycles to BOINC. Gridcoin is intended to attract people to use BOINC who wouldn't otherwise be interested if there was no personal gain for themselves. |

Do you have any backups of your wallet files? I backup once per month. I had the same thing happen to me once, when I used my backup everything re synched and was back to normal. Btw what is your hasing speed? over the last 36-48 hours. I fall out of sync 1-2 times a day, that 6K was mined over the last 36-48 hrs or so, I was periodically checking the block explorer and rebuilding the block chain as needed, so I know I wasn't forked for 2 days or something.
Hashing speed was around 2400Khs. I do have a backup from a few days ago. This is something I SHOULD know by now, but I have never dealt with it before, is it okay to use a wallet backup from before I mined those blocks? Absolutely, in fact it would be preferable to using the one that might be corrupted. |

WTF?!?!? I fell out of sync with the block chain so I started rebuilding it, and now all of a sudden the ~6K GRC I had in that wallet is gone. I did a -reindex and it didn't help. I went to my roaming/appdata directory to see if my wallet was missing or something and now I have a wallet.(longstringofnumbers).bak file and a wallet.dat file. What is that .bak file? Never seen that before.
.bak is a backup file, the long string of numbers is an epoch (unix) timestamp. Likely your old wallet was corrupted and a new wallet.dat was created and your corrupted wallet was moved to a .bak file. It sounds like you hit a hard fork of the blockchain (likely you lost connection to the internet and you have more than wallet so you you were mining on your own personal network) then when you regained internet connection the wallet realized it was out of sync with the main blockchain. There should be a way to restore your old wallet from the .bak file but I don't have any personal experience with this so i can't give you the details, but even if you restore the wallet I wouldn't count on your coins being there because it really sounds like you hit a hard fork. Yeah, but I shutdown gridcoin and rebuilt the block chain multiple times over the past few days. Was I continually mining on a forked chain for days? And like I said I was checking the block explorer to be sure I was synced. If that is the case I can't be the only one who found themselves on the forked chain, and apparently the block explorer was following it on and off as well. Yeah, sorry I hadn't seen the post where you said that when i typed that, I edited my OP as such... If you were on the correct block-chain then you should be able to restore your wallet from the .bak file but I am not certain how to do so since I have no personal experience. I would assume it is probably as simple as opening a CMD, navigating to Program Files (x86)\Gridcoin and running "gridcoin-qt.exe -restorewallet timestamp.bak" or something along those lines. |

You can have the wallet do what you are doing automatically at a set interval by setting "restartwallet=" in your gridcoin.conf Setting the interval with that flag will shut-down the gridcoin client, restart the wallet and re-build the blockchain, just be sure to also set "closemineronexit=false". |

My apologies. If you weren't forked for the past few days and you can get your wallet restored then your coins should be there. |

zulzedd - BTW, crystalmud on the order sheet is "newtocrypto" here on BCT... The link for his profile is on yesterday's order sheet...
Oh, didn't noticed this. Ok, thank you! NP my friend happy to help  |

Whoever changed my sell price from 0.0919 to 0.0949 I would appreciate it if you would stick to editing your own orders. Thanks.
It's possible to find who was that in change history. Editors - don't do this anymore, please. It may not have happened, I thought I remembered setting my price to 0.0919 because I swear I remember the lowest sell order being 0.085 and then the next lowest was 0.092 and I wanted to be just beneath the 0.092. I was apparently mistaken because I can't seem to find these edits in the history. I apologize for my mistake, this is pretty embarrassing... |

I want to use the linux guide later, thanks. I will try to get the linux guide up in the next 24 hours, I need to partition a drive for Debian on one of my boxes and do the process myself first and I just didn't get time today. I will get it done ASAP. |

Well done! I'm going to be busy for a bit but this is where I will start when I can throw some more time into it. Thanks for taking the time to do this!
No problem m8, happy to help! |

I managed to get the client sync'd again, by using the .msi, and ensuring the QT was run as Administrator (this was probably the problem before). I'm still getting the crashing when I try to run Gridcoin at the same time as Boinc, though. I've triple checked the Boinc folders in gridcoin.conf, and ensured .NET is up to date (there was an update to run). My gridcoin.conf below.. rpcuser=myrpcuser
rpcpassword=myrpcpassword
rpcallowip=127.0.0.1
rpcport=myport
server=1
poolmining=false
restartwallet=0
addnode=98.114.181.178
addnode=76.187.184.27
addnode=66.187.94.194
addnode=76.74.177.224
addnode=84.125.196.167
addnode=71.233.139.62
addnode=72.92.48.105
addnode=72.208.65.226
addnode=77.64.220.124
addnode=50.152.78.46
addnode=207.229.136.136
boincappfolder=C:\Program Files (x86)\BOINC
boincdatafolder=E:\ProgramData\BOINC Any other ideas you may have would be greatly appreciated. Should the boinc folders have a trailing slash or not? Have tried with both so that's not the issue, but just want to ensure I've got that right. I believe traderman's comment above is correct. I believe Gridcoin and the BOINC folders all need to be on the same drive... |

if i see something like that on my cgminer (i use an external istance of cgminer), is it correct? No suitable long-poll found for http://127.0.0.1:9332 network diff set to 2 new block detected on network network diff set to 2 new block detected on network and so on... Yes, that is the correct output, later versions of cgminer have a slightly different output format than the earlier versions which is why it doesn't look "familiar" if you were using an earlier version of cgminer before... |

In my case the problem was twofold - default install directory is "Program Files (x86)" on a 64 bit Windows system, and I'd changed the data directory too. Unfortunately the QT still crashes when I start it - just as the Gridcoin Mining Module opens up.  Are you certain you pointed to the correct BOINC directories in your gridcoin.conf and you didn't just copy boincappfolder=C:\Program Files\Boinc\
boincdatafolder=C:\ProgramData\Boinc\ For example, if you installed BOINC at D:\BOINC then your gridcoin.conf should say: 100% certain. Can only imagine wallet.dat was corrupted so have deleted Gridcoin data directory, including blockchain (doh) so am now trying to re-sync. Annoyingly, I'm now back to no connections to the network. Have added the addnodes and sorted port forwarding as described earlier in the thread. Any ideas why this problem persists? Hmmm, very strange. Things to double-check: 1) Make sure you are running Gridcoin as admin 2) Make sure you have forwarded the correct port as this port was changed a couple weeks ago. The correct port is "32760" 3) Try adding an exception rule to your firewall for Gridcoin |
