Just to add something. Don't know if it helps or not. I have the same problem with Limewire giving the bsod and rebooting. A couple things I noticed however. It only happens when I am connected to the internet through a wireless connection. If I disable the wireless connection and attach to the internet via wire into the router, I have no problems. This indicated to me that there might be a setting for the wireless router which needed to be changed. It was a linksys router. i have susequently moved. The new apartment already had a Netgear router set up. I was able to use Limewire through wireless with no problems. The person who controls the router then set up a password for security. It was originally unsecured. I stsarted getting the reboot again. The Linksys router also had password protection. Don't know if some of this is coincidental, but Limewire definately worked fine going through a wire connection to the router. It has only rebooted (for me) when using wireless.
