Thank you Nythain. Turns out it was Peerblocker.

Yes I have a worker setup

I'm using a nVidea GeForce GT 220 graphics card. I cant seem to find any references to it in the list of bitcoin mining hardware lists. I am wondering if I need to be worried about overheating at all when mining, and if so what can I do about it?

I'm using GUIMiner with a nVidia GeForce GT 220 graphics card, attempting to connect to BTC Guild. I have port 8332 forwarded to my computer. I am getting the following error:
"Problems communicationg with bitcoin RPC"

Suggestions are appreciated.
Thanks,
