Shouldn't be a problem that you are on 64bit, it was compiled on 64bit windows machine for the windows wallet, I haven't heard anyone else having that problem.
Odd, it happened on my Home PC, Works PC and Macbook I recon benders screwing with me!!
There was a chap a few pages back having the same problem... Lets confirm im not being slow.
1. Download Wallet
2. Add Nodes to Config file under the current nodes.
3. Load wallet
Thats been my process for all the other wallets, most didn't need any nodes adding.
try running the wallet first without .conf file, see if it syncs. then add the .conf file. i have done it like this and it worked. also if you try adding those nodes in debug window.
