my 2 home systems - XP home and Pro - used to run new BearFlix just fine until 2 days ago. Comcast digital through MS WiFi

Now neither one will connect. Host connections keep trying "connecting...", but never connect. Sometimes get "timed out" in red.

Suspect - the most recent MS security updates, which I loaded 2 days ago.

Everything in the firewall area looks OK according to your Help items.
Suspect- firewall instructions are for cable LAN, but I am on WiFi secure WPA

Pleae help if you can.

Thanks in advance
