my limewire 4.8.1 used to work on this laptop without doing any upnp enabling or port forwarding on the router side. Since i restored my laptop to its orginal state and installed limewire agen it does not connect.

however it still connects on my other laptop without upnp enabling or port forwardin through router

any ideas to fix the problem?
