I played AH before our free trial anti-virus ran out (Norton, God forbid) and had no trouble. When the free trial went out, we subscribed. We now have the entire Norton anti-virus program on our system. Now, every time I get on, within a minute of logging on, I get the "UDP lost, switching to TCP" box. Then, within another TWO minutes, I get booted, no bad frames, no glitching, just says "host connection lost."

I've added AH2 to firewall exceptions and still nothing. I know Norton is very invasive but it was all we could get at the time. Any help would be VERY much appreciated.
