It's time to do the 'point-out-the-obvious' dance....
No firewall issues?
Nothing like peerguardian installed?
Try something like NetLimiter Pro & sniff those ports!
Tried a virus & SpyBot scan (i.e. port hogging by KeyLogging Malware & the such like)?
I think it has something to do with this idiotic game my parents put on the computer... I think it messed with some of the same files, I am going to un-instal and re try.
