When I try to direct connect with a friends computer to download music from them it gives me an error message and says it "cannot connect to host computer." They also have the new Beta Limewire and the IP address that we use to try to connect is the one that is given in the Direct Connect tab where it says "When your friends want to connect to you they should use the number ....." What can I do to fix this problem? Does it have anything to do with a firewall and if so how could I disable that so that he and I can share music?
