I started an email game of CMBN v4.0 with a buddy. I started the game and sent the file to him and he accepted. The file got returned to me to do my troop purchases, but the file was grayed out in the list. When I clicked the file it said I needed the vehicle pack in order to load the game. I thought this was weird, since we were doing an all infantry fight, and I didn't think my friend even owned the vehicle pack, but I figured "what the hey" and went ahead and bought the vehicle pack. I made my troop purchases (no vehicles) and sent the file off to him. Now he's getting the same message. Has anyone seen this before? How do we start a game without him needing to buy the vehicle pack? (I don't want to force him to buy it in order to play).
The game I started was June 1944, small battle, American Paratroops vs. German Army, Infantry only for both sides.
Thanks for the help.
