Thanks, Edwin. I'm now playing EB.

Something you might be interested to know, as I think this might be causing problems for others who have been crashing at the same spot:

It seems that whenever I install the rtw patch upon reinstalling the game, it results in the game CTD whenever I hit -mod:EB. As long as I do not install the patch, EB works fine. I don't really mind though, as the patch only seemed to fix problems my mac wasn't experiencing playing rtw.
