Stopped working?

I've only up until tonight had no problems with crashes. After booting up the kaiserreich mod, selecting a nation, and pressing play my game crashed. The crash came up with a small window saying it stopped working. I then tried dh full and dh half, both worked fine but after quiting out of both the same window popped up again. After uninstalling and re installing the game and the kaiserreich mod i've still been having the same problem.
