I got this constant problem with LW. Everytime I open it up it will ALWAYS close up on me after a certain period of time. It always happens at random and I can't seem to figure out what the heck it is. I run MS SP2 and I got LW PRO 4.2.2, run Internet Explorer 6.0. I opened the ports through my firewall(6346 TCP/UDP) and also selected it under the advanced options in the LW program(Force IP/Port 6346). I can go all the way up to having a turbo-charged connection quality, thats not even whats wrong, as a matter of fact, I'll be turbo-charged within 20 seconds of opening LW. It's like it says, "alright, thats all the Limewire you get for right now," and then kicks me off. I can open it up again right after it closes itself, but it will eventually close it self again. It seems like I'm the only one with this problem, I didn't find any other threads relating to this exact situation.
