Until yesterday I was running Windows 98, Limewire was running great and had never had a problem with it. I just got Windows XP SP2 (same hardware, though) and it's all turned to ****.
Strange thing is, it was working earlier on, and now it's suddenly not connecting.

So

OS Version: Windows XP SP2

Firewalls: None that I know of. I turned Windows firewall off, I have Norton Antivirus, but not Internet Security. I have Microsoft AntiSpyware Beta1, I'm not sure if that even has a firewall but I disabled it anyway.

RAM: 512MB

HDD Space Available: 22.3GB

Connection Type: 56k

Location: Home

Versions:
LimeWire 4.8.1 PRO
Java 1.5.0_02

Any help would be greatly appreciated.
