Well it may be, but the OP says he can unlock it so I want to try.

Also, I am done with Multibit Wallet. I have seen first hand that it can screw up.

I downloaded the zip file, but it will not extract. I am sorry to be digging up such an old topic, but it is the only relevant one I have found.

It is possible that the Multibit Wallet I have installed is corrupted or something. Here is what happened:

I was going to send a small amount of bitcoin to a friend. Multibit prompted me for my multibit wallet password. I use one of three passwords for all nonessential accounts. I entered the passwords, and multibit said they were incorrect. I started trying different\ combinations of wrong keys, like one key over or reversed caps/lowercase to no avail. I then made another wallet in multibit, and entered the password I mostly use for these things. I then went back to trying to unlock the other wallet. a few minutes later I went back to the newly created wallet and tried to remove the password I had just entered and written down exactly. Multibit gave me a warning of "can not decrypt bytes". I looked up this error message and the software creators say this means you entered the wrong password. I kept trying, again to no avail. So I closed/shut down the multibit software and restarted. I tried again to remove the password on the new wallet, this time it accepted.

I am running version 0.5.13 of multibit wallet. It is my thought that for some reason it is corrupt, maybe just the installation on my pc, but somehow it has not stored my password correctly. Of course it is also very possible that I just fat fingered or mistyped one letter or number twice in a row while creating the original wallet. Anyway, I would really like to unlock this wallet and get the bitcoin out of it. I have not problem paying the OP a fee of 5%, because if I can not unlock this thing, then I lose 100%.

Does anyone know of a brute force program that will work with Multibit? Has anyone tried one in the past and have experience with it? Any help would be greatly appreciated. 

It looks like the USB 3.0 ports on my pc may have a problem. I plugged the Anker USB hub into a USB 2.0 port on my pc and it seems to be working now. I still had one ASIC that didn't start up, so i pulled it and plugged it into another port on the hub, all seems to be working now

Thanks to everyone for the comments and advice. I also have a fan on them now

Thank you Blackswan, I bought my first ASIC miner at the beginning of October and dl'ed the driver then, I didn't realize that a new driver was released so soon after. I just dl'ed the new driver and am giving the hub another try.

No, it finds them. The PC and the client both see them. It is just I either get errors in the client OR the client says they are all working and they are not...

Thank you for the replies

I have tried unplugging the ones that stop working and plugging them back in to a different port, one at a time... still have problems.

I do not think it is cooling, they run fine on the pc ports with no fans on them. When I had them in the hub, I has the hub sitting on top of my pc, with the top exhaust fan I put in the case blowing across them. The ones that were running stayed a lot cooler than they do on the pc ports. The USB hub has a 5 amp power supply, so power should not be an issue.

I was thinking that it could be a problem with compatibility between the miners and my hub, but I did research and a lot of people use Anker USB hubs for the same type of mining that I am doing.

I have read that mining is not profitable, and using the 333 mh usb miners is even worse. I am just trying to see if I can do it, and hey if BitCoins stay around for a while it will be profitable If I can work this out and get it working on a Pi, then I will be building a faster mining rig. I am only spending discretionary money out of my monthly budget. So instead of going to the casino in town or going out to bars with my friends, I am buying stuff to mine it is a lot more fun to me. Plus I am a techno geek, well I also like mechanical things. Besides electronics I also like working on old mechanical watches.

Hello, I am new here and new to bitcoin mining.

I am having a problem, and I have searched for an answer, with no success.

I recently bought 5 usb asic miners (333mh). I use BitMinter, and with all of the miners plugged into my pc's usb ports everything works fine. I want to buy more miners, and possibly a Raspberry Pi, so I bought a USB Hub. The one I got is an Anker 9 port usb 3.0.

I plugged it in to one of my pc's usb 3.0 ports. I waited for the pc to recognize it, then plugged in each of the five usb miners. I waited for the pc to recognize them all. The green LED lit up steady on all of them.

I started BitMinter Client and hit start.

Three miners started working (LED went out and only flashed slightly intermittently), the other two stayed lit solid. After a while one of the others that was working lit back up steady green.

I went through unplugging them and plugging them back in one at a time, tried many different things.

I finally got the BitMinter client to say that they were all hashing, but  after a few minutes the LEDs lit up steady green on all five. The client still said that they were hashing, so I let it go for a few hours.

I checked the BitMinter webpage to see what my work per shift was, and was getting about 160 mh.

I pulled all five and plugged them back into my pc's usb ports. They are all running fine again.

Question, is there some change I need to make to the BitMinter Client so that it works with the USB hub? Is there some usb 3.0 software/firmware that my pc needs in order for this to work? Is there some procedure of plugging the miners in to the hub that will make them all work plugged into the hub?

Any help or advice on where to look for an answer will be greatly appreciated.
