I just started receiving this message and am unable to connect to AH. I'm getting a popup window saying "If you are usig a firewall such as Zone Alarm, you will need to allow Aces High access to the Internet".....etc etc. Eventually it will ask to try an alternate route, which will in turn fail.
I use Kaspersky, and AH is setup as a trusted app there. I can connect without issue in various other games. AH is the only one with issues, although it connected fine yesterday.
Any ideas as to what might be causing this?
