Just upgraded to CFP 3 from 2.4 and when i restarted like it asked i could not connect to the internet at all. I tried to add a trusted network and all of that lovely stuff. But still couldn't get connected. So now i only have windoz firewall since i had to delete CFP 3 to get my connection back.

Specs:
Windows XP Media Center Edition SP2 (updated) all 32 bit
Intel Pentium 4 3.06 GHz
512 MB RAM
