hydro peroxide crash
 

every time i press the red on and off swich for the hydro peroxide my game crashes. is there a way to stop that?

Are you running any mods that change the Type XVIII or the German side of things? Short of that, the only other thing I can think of is to reinstall the game. Uninstall, then delete the Ubisoft folder in the Program Files folder. When uninstalling, when it asks if you want to keep the saves, choose no. Reboot, then reinstall the game.
