I'm running cuda miner (I've an NVidia card) and have tried connecting to both mining.bitcoin.cz and api2.bitcoin.cz, but the client is always stuck on "connecting" for the speed.

Here's a console dump:

2011-07-14 14:53:43: Running command: C:\Documents and Settings\Cyclone\Desktop\bitminer\guiminer\miners\puddinpop\rpcminer-cuda.exe -user=***** -password=***** -url=http://api2.bitcoin.cz:8332
2011-07-14 14:53:43: Listener for "Slushy" started


I've left it like this for a couple hours and it's still stuck on connecting, I've already got a full set of blocks in Bitcoin itself...what can I do to fix it?

If I try to switch to RPCMiner's CPU client, it just says "Connection problems" regardless of which URL I try. I've checked my firewall settings multiple times, to no avail...
