AAh, ZoneAlarm and ATOC full edition.
I think most of us are using the Express editon, so myself is not familiar with the full.
As for ZoneAlarm, it could be as simple as shutting down to medium cover, or even trying turning it off as a trial.
I use McCffee Personal Edition and have had no trouble, just had to set up my router ports and turn OFF UPnP.
Yes UPnP has to be turned off on my system before I could get through.
