I didnt have the XP firewall on-must have turned it off forgotten about it!!
Tried changing the settings under firewall configuration in LW for the listening ports and the other one but LW froze every time i tried to change the listening port (the one about P2P sharing was ok)
Tried deleting my Java and installing the new one but still no luck!!
Spoke to my ISP and he said that there may be a SYSCO router???
Any more ideas??
