Recently when I try to run LimeWire (it used to work a week ago!), it shows the splash screen but then a dialoge pops up saying:

"LimeWire was unable to initialize and start. This is usually due to a firewall program blocking LimeWire's access to the internet or loopback connections on the local machine. Please allow LimeWire access to the internet and restart LimeWire."

I have removed LimeWire (and javaw) from my Windows XP Home Firewall exception list (so it would ask me again) and have added the ports to the list (as LW suggests). I have also reinstalled (over top of the old one) and also uninstalled and reinstalled.

Nothing....

also, I dont get a prompt to allow javaw to access the net... I know JAVA and have the SDK, so i know i have it. And also, if i need to change the ports, how can i do that w/out opening LW?
