...it seems to me that you didn't disabled QMBPlus.

When I had both QMB mods enabled in the same time my game also crashed at ~65%, try to disable QMBPlus and than see if QMBMinus is working for you.

Please report if this solves your problem.

Well, there are 11 QMB files in the mod's main folder. When switching to QMBminus I simply replace them with those of QMBminus. Is there another way to disable QMBplus?
