I have been playing the mod for a while, no problems, go to play today, and my shortcut is telling me "eastern front mod does not appear to be installed on your system. Try reinstalling Eastern front to continue."
So, if I go in and check my path location, everything is still good, the odd thing is if I go into "settings" turn off auto update and just run the game its fine. So the shortcut still sees the game when I actually launch, but when it tries to check for updates it can't find it.
