Bing Maps not showing in PowerGeopak when connected for firewall

I've been able to access Bing Maps in PowerGeopak when I'm either on the wifi or from home, but from our offices i get a message "At least one raster reference was not found".  I have a valid Bing license and like i said, it only fails when connected to our LAN.  I've wiresharked it and reviewed what i could but i'm not seeing the issue.  Any help at all would absolutely be appreciated.  

PowerGeopak SS10 V 08.11.09.918
