Okay cool. I did try doing something similar before, by taking what appeared to be the private key out of the wallet.dat file and importing it elsewhere, and it showed my balance, but it wouldn't let me transfer the coins without 'proof of work'. I read online and I was lead to believe that I needed something more than just the private key for original mined coins in order to transfer them.

And I won't be rich, unfortunately. I only left it on for only a week and mined a single block, back when you could actually do so from your home computer. If only I had left it on for a couple of months back then I would be rich, though. This will only help me dig out of debt and maybe make a downpayment on a house.
