I've been downloading music to my shared file from my personalized cd collection plus downloading music from Limewire. It seems that every day or so whether I turn off my computer or not that they come up as missing. I am using Limewire 4.10.9 Pro under Windows Media Center 2005 with SP2. I have run a virus check on my system and found no errors. I have not stopped sharing my files. My firewall is always up. The only exception is when I have to restart Limewire because the indicator for my firewall is gone. Can Anyone help me please....
