I think what the devolopers were trying to do is help people running through routers with the UPnP technoligy. While 4.8.1 worked fine for allot of people there were allot of people that were haveing problems. For some reason I cannot duplicate the problem that you are having, If I remove my router LW still works thus I have not been able to troubleshoot the problem. I am working with another that has the same problem but he is curently off line and it is currently at a standstill. I have a copy of 4.8.1 on my hard drive and was going to E-Mail it to him and see if installing it would solve the problem for now. So I will let you know if we find a solution.
