Chill out, all you anti-Microsoft fanatics (and get used to computing securely BTW), Limewire works with SP2.
2 steps:
1. The first time Limewire runs, the Windows Firewall should prompt to enable 2 programs: "javaw" and "<installation_path>\LimeWire.exe". Enable these 2 apps to pass the firewall when prompted.
2. Per Limewire's own instructions (
http://www.limewire.com/english/content/firewalls.shtml ) go to Start | Control Panel | Windows Firewall and "Add port..." 6346 twice with the default scope, once for TCP and once for UDP (the names you give these rules aren't important).
Ta da, Limewire works. Amazing, Microsoft did not ruin free computing everywhere, it only enabled 90% of the computers on the planet to connect to the Internet more securely. This should make you happier on its own, even if you ARE running Linux. :-)
Cheers,

PS To be fair, before I put this together, I installed the "Event ID 4226" patch from
http://www.lvllord.de/?url=tools --which did not help on its own, but I don't think its current installation is crucial to the solution. If the above steps do not work for you, try the utility as well. All I know is Limewire's connection quality is now "excellent" and files are uploading and downloading as before SP2.
PPS I've upgrade to Limewire 4.1.5 Beta.
