Mac Gaming Mods

I downloaded the mod called Mp3, whenever I try to play a quick mission it always crashes.
First time when I selected some specialist, and the other time when I tried to play that tower of terror (or whats it called) map.

What is going on here?

I have Desert Siege and Island Thunder activated, so that shouldn't be a problem I guess.

My first guess is the mission is missing something that allows it to be played in single player. You could check with the person that put the MP3 mod together to see if they know about the problem.

I didn't get a readme file with the mod, and I didn't save the link.
Do you happen to know an official link for it?

I think bigtex on GameRanger compiled the map pack. If I could find the original mod that the map was taken from I could check out the mission, without having to download that hugh MP3 mod.
