Thanks for your help.

I'd already tried deleting prefs while closed (more than once...in case it didn't take the first time ).

The thing that doesn't make sense to me is that I've used LW for years now with this set-up (whatever UPnP is), why would there be problems all of a sudden do you think?

I'll look into the port forwarding stuff now & let you know how I go.

EDIT: No luck with the port forwarding.

Any other suggestions? *crosses fingers*
