13. Do you see a brick wall in front of the blue world icon at the bottom of LW's interface?
yes i do.

As i metioned erlier i have upgraded my old laptop (running win xp sp2) to a new 1 running xp media center, i used to be able to run limewire on the laptop but now it wont connect. my wirless hub uses unup and automatically configure for the gnutella network i have also set all the port on my avg internet sercurity to the correct port, but i still cant connect, if you could tell which specific protocol the gnutella network uses i could create specific rules . also i cant use the ftp protocol on media ceter if that helps the solve the problem
