I can't get Macplay's AVP2 multiplayer to work in Panther either. I called them and they said it was a protocol problem with Panther. I got the same message you got. Can you say cut and paste. Did you notice the graphics are a little faster in Panther? Especially with the marine shoulder lamp. Anyway its been a long time now since they have known about this problem and I have a feeling they will never update AVP2. They'll take the money and run!!!
well, I frigging hope not, cos ive had it less than a month.
I only bought it for the multiplayer aspect, thanks a lot people, you've done your reputation the world of good.
