As you already discovered, the .exe does nothing, but since my bug report falls under this same category, I figured I would put it here as well.
First off, I just have to say that this, in conjunction with a TC I am working on for a game called EV Nova, is quite possibly the best TC ever!
Anyway, the reason I finally got around to registering is this: I noticed that the various files cause JK to crash in single player on my Mac. I singled out the three trouble files, which are as follows:
mapextras.pk3
MenuScripts.pk3
SgehSource.pk3
Not sure why these cause it to crash, but it does. The game seems to work OK without them though. Also, the categories names of people in single player do not show up, but that may have something to do with the removal of those three files.
