Ok, you pulled the most recent blockchain data files.  You can't just replace your existing ones because that set doesn't have the third file, the blockchain index.

So what you can do is copy or move those two  (blk00001.dat and blk0002.dat) to a temp directory (e.g., C:\Temp ) and then do

 C:> bitcoin-qt -loadblock="C:\TEMP\BLK0001.DAT"

This is explained here:
 - http://bitcoin.stackexchange.com/a/4148/153

And it should load the blocks.  If it doesn't then go ahead and wipe everything except your wallet.dat from your Bitcoin directory, then relaunch the client using the -loadblock from above.

I'm not sure if after it is done loading from blk0001.dat if it automatically loads blk0002.dat or if you need to stop and restart the client with -loadblock= to get the blk0002.dat loaded then as well.
