hello again

am now trying to sort out my friends computer to connect to lw. done everything the same, but to no avail.

bottom right hand corner on lw has red blocks not green, is this anything to do with lw not connecting?

Windows XP
14/8 GB free space
external wireless broadband modem
BT ISP
Java J2SE runtime environment 5.0 update 11
not sure of any other details
