How do I get my Bitcoins?

Hi I thought I had this figured out but apparently not. Again thanks for your patience, I'm definitely a Nube.

I'm running windows 7 64 bit. I have established two cards running on two different computers and am mining with BTCGuild.com

1. I accumulated 2.6 bit coins and asked for a payout. It sent it to the address that was on my account. I must have entered it at sometime.

2. I realized that my bit coin app wasn't running, so I tried running it and got the dreaded Error loading blkindex.dat error. Looked around and found out that I was suppose to delete the blkindex.dat, and blk0001.dat files in my app data directory.

3. Ran the bit coin app successfully but no bit coins have showed up? I also tried copying my 'new address' into Btcguild and requesting a payout to see if it comes to my new address. I also before copied the address from btcguild into my bit coin app thinking that the coins might show up eventually.

What am I doing wrong? Are my coins lost forever into collective. Where should my wallet be. Right now its in my appdata under bit coins. I also copied my bit coin wallet into my regular bit coin directory.

Any hints or help would be appreciated. Even if I've lost my 2.6 coins I don't want to lose anymore.

Thanks
