I have two identical computers, using the same router and ISP, the only difference is that one runs VISTA and the other runs XP SP2. The computers that runs on XP SP2 runs Limewire pro with no problems, but the computer with the VISTA will not connect. It says "connecting" but just stalls there and does not actually conect. I've checked the Firewall and I have Limewire as an exception. What else could be stopping me from connecting?
