Question #1: I would like to set up Bitcoin QT on several computers. Can I load the blockchain to one computer and copy it to the rest? If so, how? I have tried simply copying all files names blk*.dat (5 of them, including blkindex.dat), but I get fatal errors on the target computers. Should I be copying other files (.lock, db.log, debug.log, peers.dat, and/or the directory named database)?

Question #2: I have another problem: I set up Bitcoin QT on a computer that I will never connect to the internet, generated a receiving address, and sent a few coins to it, a few months back when a few coins were worth pocket change. Of course, the coins were never received, though the network processed the transaction. Now, those coins are worth several hundred bucks, and I'm trying to recover them without attaching the computer to the internet. I tried saving the wallet.dat file and using it on another computer that has QT installed and the blockchain up-to-date. It loaded up OK, but reports a zero BTC balance. What did I do wrong, and how can I correct the problem?

Although I am a "newbie" to the Bitcoin Forum, I have been playing with Bitcoin for quite a while and am quite technical, so you can be specific in your response. Thanks!

I can write you some pointers if you are still in limbo.
