I have used Ghash.io for 5 months. The difficulty goes up and income goes down. End of June this year I bought 2 pcs S2 Antminers for 4000 $
Got good income first month, but it declined month after month. I am now down in 0,5 btc/month and that does not pay electricity bill.
I am now closing down this gambling, I lost 1000$ on this game. I strongly advice you guys not to start this game. Even if you buy a cheaper machine, it will be obsolete in 3 months time.
Those who win is probably those who buy and sell bitcoin.
PS. I am in Sweden where power cost is very low, but still no chance to reach ROI
The winner here is the electric company and those who built the machines. The naked truth!

ok, so i moved my bitcoin to the other wallet plus on a usb.
Made an uninstall of bitminter on my stationary one, but that did not complete.
When I try to uninstall it now, I get message to wait (have done for hours   )
"please wait until current program is finished uninstalling or being changed"

Made a new install, but that did not help. same message, error opening etc. etc.
So how to uninstall all and start with a new one ?
Can not uninstall via control panel, program and f.

Shorena,
 I tried to follow your advice, but bitminter opens with same error and question, then when clicking on abort or ok, it close down.
That is on my stationary computer.
It refuse to start normally.

I use win 7 on that one, and win 8 on the laptop.
could not get "run" on the laptop, probably different?

Gave it a try, copied the wallet file to the laptop, opened bitminter, and Viola, there it was, as nothing happen.
seems like my day ends with sucess at last.

Will uninstall bitminter on the computer and reinstall it.

Thanks,
 I have no coins on the laptop, only installed the program. Reason; will be out of country later this year for a long period, so I wanted to bring it with me.

So I delete the unused wallet.dat file on the unused bitcoin program on the laptop, and replace it with the backup one I have now, and then open bitcoin and it will be running as the other one did. Correct?
Later I can make addresses between them and send bitcoin back.
Got this knowledge so far

If Bitcoin still is corrupt, and i uninstall it, will even the debug, chain, database and blocks be deleted, or will they stay put?

I learn every day, sometimes from huge errors I make

Hi!

by continue searching, I found the wallet.dat file. It was under Appdata roaming bitcoin. Found the answer in this forum, THANK YOU GUYS!!!!
Made a copy to an another hdd, and will now copy to a usb memory.
I was not aware of that the bitcoins was stored in my computer that way, I am new to all this.

Also I have Bitdefender on my PC, and have today got help from them. I have sent logs to them to check the entire computer.

Since bitcoin core does not work now, should I uninstall it?

I do have bitcoin core on my laptop as well, can I copy the wallet.dat file to the program there?
how to proceed?

I make a new thread, since the other one is old:

Hello guys, I will try to lift this thread and tell a story about a strange behavior on my PC two days ago.
I have had bitcoin core on my PC for just a few days.
I believe it all started with with FSX Flightsimulator did not start up. I made a repair on it, and was reading tips on the net how to get it up and running again.
I was not able to solve it that night, and closed down the computer.
The next morning i connected to the net, Mozilla Firefox would not start. Or, I got the message it was already up and running, but it did not respond. Following advices on Mozillas home page
did not help, it was not to be seen in task manager, or not possible to close it anywhere. So I uninstalled it and reinstalled the program. Then it worked fine.
What I discovered at the same time, was that several icons on my desktop had disappeared.

And today when I wanted to open bitcoin-core, the icon was gone, even on the start menu.
I had to go to the files, and start it from the exe file. When starting, I got the messages you guys had here. Made a try a couple of times, and downloaded a new one, but same result.

Looking in the file folder, I find only these files:
daemon
doc
bitcoin-qt.exe
copying.txt
readme.txt
uninstall.exe

Should it not be more files?

Now, this morning I am trembling of nervousity, have I lost my bitcoins??

The HDD is only one year old, I have 300 Gb of free space.
Yesterday I did a maintenance with AVG PC Tune up and Bitdefender. That was after the icons disappeared on the desktop.

Can also mention that AVG PC Tune up, also have a strange behavior today. It give a error message and ask if I want to send a report.
Then it crashes.

I guess it will not help to make a system recovery?

Been working with computers for many years, but this is a new experience.
If I have lost the bitcoins, as I today understand, probably is stored on the pc, I am in chock.
Tried to read through this thread, but can not keep my mind clear. Besides it seems like my problem here is of an another dimension.
I use Bitdefender total security, but still, there could be a hidden intruding from outside....

"Server network looked like it was unstable for some seconds. Just long enough that some miners lost their connection.

If your miner(s) didn't reconnect quickly you may be running an old version of cgminer or bfgminer and need to upgrade. Old versions could get stuck on the backup pool forever or simply crash when the primary pool went down. Recent versions have much more stable backup pool support. Taking a minute or two to get back on the primary pool should be considered normal though."

I am using a brand new S2, woth updated software, and it did the same, switched to Pool 1 from Pool 0, and today it is mining on both.
Would it be an idea to switch it of and on to reset it? Seems to have been mining on two pools far a day now.
Have no experience of this yet.

Very interesting thread and forum.
I have been using Bitminter for some weeks now, and I discovered that it was around 6000 workers when i started, now it is only~4700.
Does it means that people move to other pools? Or just miners who are down for short or long time?
