Yeah, I run spybot regularly. I don't think it's a firewall issue either. The odd thing is, some stations would work just fine, while others wouldn't. The error message I was getting said "couldn't connect to server" (I forgot the specific error code). I uninstalled mp9 and installed mp10 (yeah, maybe not a good idea to get the new version of anything M$) and it still didn't work.
Today it does.
Weird.
