firewalled on limewire

[monolithmaji]

On my home network i have two computers one running vista (the one i use) and the other using xp (the one that configures the router) and a laptop that runs on the wireless network using xp. The router is a linsys wtr546 router. When i try geting on limewire on my vista computer it would say it was firewalled and even after doing the listen port and seting the router to allow limewire it was still firewalled. I even installed it on the xp computer and just ran the broadband cable to the computer completly negating the router and it still said it was firewalled (I even turned off all the fire walls on the computer) so were could these firewalls be that are blocking my connection?

Also im not familure with limewire even though it is firewalled it still gets some connections ... has it gone the way of kazza were the downloads are just viruses and spam because when i search for something i get about 400 programs listed as what i typed in but there all about 200kb and wont open on my computer cause it detects add ware or a viruse. Or is this just because im not connecting on all servers?
