I have heard of Telia. Can't remember whether it was good or bad though. Disable your XP firewall & make sure your Norton firewall is properly set up to allow LW;
Configuring Norton Internet Security. Then restart LW & let it settle. Give it plenty of time.
If more than one of you use LW in the same day thru the same router, it might be a good idea to reboot between to see if that helps.
