Same problem. Tried reinstalling. Run weekly virus scans, and bi-weekly spyware scans (Adaware, Spybot).

OS = MSWindowsXPHome
RAM = 1 gig
Processor = Pentium 4 3.4g
Video Card = NVIDIA GeForce 6800
Limewire version = 4.9.30
Java version = Java 2 Platform Standard Edition 1.5.0_04-b05
Connection = 100kbps Intel 537EP V9x DFV PCI Modem
Router = Broadcom Nextreme 57xx Gigabit Controller
Firewall = Windows firewall
Anti-virus = Norton 2004

Limewire was working fine. Then one day it started crashing my computer. Less than a minute (but not immediately) after Limewire starts everything freezes up and you can't open the task manager. You have to turn of the power to restart. Any help would be greatly appreciated. Including any other decent file sharing software (not KazaaLite, Soulseek or Bittorrent).
