Mine won't connect either and believe me I've read and tried everything. Ports,Firewalls,latest Java, deleting SP2, you name it. Un-installing, re-installing you name it. It worked fine for about a year then all of a sudden it just wouldn't connect? I went so far as to install it on my laptop and it won't work I even wiped the OS and tried loading LW again. Nothing?
It seems there are lot's of suggestions but nothing seems to work, there is a serious bug that affects some and not others I have friends that have no problems at all very frustrating.
