I already tried to get this resolved in the mining forum, but nobody could help me. Basically, whenever I try to mine for bitcoins, either from the bitcoin client (I know it's pointless) or from GUIminer to slush's pool, I get stuck on 'Connecting'. I've tried disabling the firewall (Win7), but it still won't connect. I'm trying to use either the CPU or CUDA miner (i7-930 and GTX 460).
In fact, the Bitcoin client itself hasn't even been able to download the blocks required to authenticate itself, and just shows '0 connections'
EDIT: I've been able to fix the problem with the Bitcoin client by placing my computer outside the router's firewall (A temp. fix, probably not a good idea to leave it that way), but I still can't connect through GUI miner.
