I haven't tried it (I don't have the time, still), but I thought I'd offer a suggestion regarding this:I'm having the same problems with KarBOOM, obviously, and am bothered by the idea that many users will probably try it, see the crash, and give up without ever investigating it. This is even more of a waste since most players will probably never attempt to host a game.

So in my next version I'm going to have another small application in the same folder for opening ports, which my game can call and use to open ports by command line arguments. If there is a crash, it's in the external program, and it'll only happen when players try to host instead of when they first start up the game. Perhaps it's worth trying that yourself.
