Just thought I'd let anyone trying to figure this problem out that my Limewire is now working again (and has been for a solid week now). My PC had no viruses on it. I had Norton 2005 and had been performing weekly scans that came up with nothing. I removed Norton and switched to Nod32 to see if that would find any viruses. It didn't, but when I tried to run Limewire after making the antivirus switch, it worked. Possibly a conflict between Norton 2005 and Limewire was the cause? I don't know. All I know is that my Limewire is now working. Thanks for the help! : )
