Back in June I was mining just to see what it was all about. I grabbed bitcoin-qt, generated an address and put that address into the payout info of my account at the pool I was mining in. I told it to send to my wallet for every .5 coins mined and during the time I let it run I managed to accumulate just over .5
I eventually quit running it, and sort of forgot about it. I later formatted and re-installed, but I remembered my progress and backed up the folder containing my miner and my wallet. Now it's Dec and my .5 coin is worth a bit of cash. However I didn't export or back up my wallet, I just copied the folder. Since there was no install routine I figured this was enough to preserve my addresses.
I still have the address I told it to send to and I can see the payout in the block chain and I see my address waiting for the payment. Is there a way to put this address into my wallet or am I out of luck?
