Hello!
i have recently installed this mod as it was recommended to me by a friend, I have installed it with no problems, however joining games pops up with this message:

I have been launching the game from said launcher, but this keeps popping up, any ideas on whats wrong?

Ever tried to reinstall Movie Battles II or repair launcher? Those could be a fix but devs will get back to you. Thats odd never happened to me.
