I have Windows XP on with Zone Alarm. I start up no problem and downloads start out just fine. After about 5-10 minutes my computer freezes up and I have to turn the power off to reboot. I also get an error message that Limewire cannot connect. Why is this happening and how do I resolve it? I tried the other fixes where people couldn't log on at all. I don't have that problem, I just can't get it to remain logged on. Please help.
