Service Pack 3 was installed on my XP computer while BD was active---I immediately lost connection to internet. After some research I found a hotfix on Microsoft website and got it installed while is safe mode. Now I can get on internet but only if firewall is totally disabled---it will not bring up a webpage at any level of firewall. Everything seems to be working fine now but I would prefer to depend upon BD firewall instead of windows firewall. Has anyone come across this problem? Suggestions welcomed.
