I had the game installed and it worked fine except for being impossibly slow, so I tried reinstalling it completely (in a new bottle) and then installing the Fallout 2 Restoration Project, as suggested in a prior thread. That fixed the slowness, but now I can't load my old games, nor save new ones (I just get an in-game error message when I try to save). Anybody else encountered this and found a way around it?
I'm running it on a MacBook with OS X version 10.5.8 and Crossover Games version 7.1.1.
