I got bored of the regular game and decided to play a Coop game over Lan.

The problem is that I don't think I can create the game and neither can my friend.

Every time, the host can only select the Map, # of players, difficulty, and enemy density. I can't create the game without launching the game. Once I launch, I go into lone wolf mode.

When should my friend try to join? If he tries to join before I hit "launch game" he can not find the game. I can not even create a game name.

The only thing I can figure is wrong is that it says, it needs a 128kbit connection and over hamachi, I'm pretty sure we have that.

We are trying to play this over hamachi. Can anybody help me out? Does it matter that I'm on Vista and he's on XP?

Okay now I can see the game, but I can't join.

After the loading screen it just turns black and after a minute, it would say

General Protection Fault!
History: DareObjectFactory:areObjectFactory () Address = 0x109416f0 (file name not found)...

Any advice?
