I am new to the forums. I've had LW for about a year now and just lately it stoped connecting. I don't know y but it made me very sad

My specs are:
Windows XP
Norton Protection Center
Spy Sweeper(if it has anything to do with it)
LW ver: 4.12.11
Java ver:1.6.0_01
Dsl
Router (but it has never casued any problems)

I have been able to connect before in the past.

Thx any one who helps me out!!!!
