I hope you can help.
After being logged on 15 to 30 mins, I lose the ability to transmit through voice (both channel and range). Shortly after, I lose the ability to hear squaddies and range. Game sounds like engines and guns remain normal.
If I try to relog, I have to close the game completely. When I first log off I get the message about my firewall and "unable to connect to game manager". (by the way, if I log off while vox is working that message does not appear)
Hope you have a suggestion.
