Missing bitcoins or wallet?

I've been mining hard a few months back with my GPU and obtained a few cents, not many but enough before i received my ASIC from BFL last week.

I had my wallet on my old hard drive, made a back up of the wallet (i think i encrypted it), and kept it (a copy) in a usb drive.

THen made even a third copy in another hard drive... And now

i run again my bitcoin wallet and my bitocins are not there :(((

even when i check my receiving address it even doesn't match the addressi used to received my bitcoins (made in the eclipe pool, the transactions are stored there with my -missing- bitcoin address)

So now i dont know how to get back my bitcoins, i dont know what happened here, has anybody stolen my bitcoins? Why isn't my old address showing up when opening my wallet since i didn't delete it? Are my bitcoins encrypted anywhere or what?

I dont know what to do :((

If you re-install Bitcoin-QT or move/rename the wallet.dat file then it will automatically create a new file with new addresses and a zero balance. It sounds reasonably likely that that's what's happened.

The first thing to do is see if you've got a copy of the original wallet.dat file.

Don't delete or overwrite any wallet.dat files (old or new) just in case you're confused about which is which. Clearly label them with something meaningful, such as wallet.dat.fromUSBstick20130203

Did you restore an old wallet.dat file to use with a new installation of the client? If so, did it accept your original wallet password (in which case you did it correctly) when unlocking the wallet, or did the client get you to enter a new password for locking the wallet for the first time (in which case it created a new wallet)?

This is not the proper place to receive a proper answer, but I'll give it a try.

I'm guessing the answer is "or what".

I hope this helps.

Ok i tried to find a wallet.dat file, but i only found one.

I have several bitcoinwallets around my hard drives, and when i open ANY of them im always "redirected" to same one, and showing the same wallet address.

This is quite strnage, it look like all these files are invoking the bitcoin program installed on my os, should i uninstall it?

celtician this is not the correct place to ask your question... in fact, I don't know where on Experts Exchange would be the correct place.

Certainly I suspect that the procedure that you used to "make a backup of your wallet" might be the culprit, and I hope you still have the old hard drive, but I'm not a bitcoin user, so perhaps you should try asking in the bitcoin community at http://bitcoin.org/en/community

Here looks like the best place:

There isn't really a particularly suitable topic area for bitcoin on EE, so I'll continue to help you with this here if you like. It's true though that bitcointalk.org is a very active site for getting Bitcoin related help if you need it. I would avoid sending anyone you don't know your wallet though; there are lots of scammers out there in the bitcoin world.

I've done a couple of years of amateur mining with a graphics card, though I haven't upgraded to ASIC hardware so I stopped mining a few months ago when the difficulty rose too high.

Let me know how you go anyway.

Sorry, I didn't notice your latest comment, and I only just now got an alert for it.

Are you double-clicking your wallet to open it? If not, how are you opening it? Are you running Windows? If so, what version?

The Bitcoin-QT client is the most common client; is that the one you're using? If so, the wallet it opens is the one specified in its settings and no other.

Are you using Windows? By default, the application data, including the wallet file, sits in %APPDATA%\Bitcoin (you can copy and paste that address into windows explorer ie the windows file manager)

To change the wallet file that Bitcoin looks at, rename the existing file %APPDATA%\Bitcoin\wallet.dat to something like %APPDATA%\Bitcoin\wallet.dat.old (preferably something more meaningful) and copy in the wallet.dat file you want to open.

Once you've done that, you need to tell the client to rescan the wallet. Do this by running the client from a cmd prompt like this:
bitcoin-qt.exe -rescan

There should be a Bitcoin section within EE : )

Im trying your options now and will let you know what has happened.

It would be nice if EE accepted bitcoin as a payment too. Would only make sense.
