Unable to use p2p programs



All of a sudden Limewire and Bittorrent can?t seem to connect.
Bittorrent gets hung up, saying "Checking for firewall". Limewire
says something about not being able to make a connection. I have
tried restoring from a previous restore point and I am able to use
both programs until next reboot. I have tried closing Trend Mircro, my
windows security centre is disabled. How do I solve this problem or at
least how would I find out what?s causing the problem?

Any help would be greatly appriciated.
