I have the same problem also. It locks up and crashes. Also in the new patch is ver 1.2. There is different vers of the game. There is one for dx9 and dx11. Total different files. I have mail the exe of them off to chris.
I am using MS.NET Framework 4.0.30319 and version 126.96.36.199 of Iron Sky Invasion and I cannot get any trainer to work as described. I did try trainers for the steam versions and they just crash the game as soon as I hit F1. The trainer for the original version doesn't crash the game, but it also doesn't do anything in the game. I got my game direct from TopWare Direckt online and unless they tweaked the game without changing the version number, I can't get any trainer to work. Any help would be mush appreciated. Thanks.
