The error is caused by something blocking your connection or it being dropped. Such as a firewall, blocked ports, antivirus, etc.
However I have been unable to solve the issue. I reformatted my computer, installed vista and 7 (tried one then the other), directly connected to the modem instead of router, turned off windows firewall, tried a proxy and changed DNS.
I am completely stumped, and can only think it might be an ISP issue at this point for me.
If any of you figure it out, please share your method to fixing it
