I've installed the Baldur's Gate series onto my Mac and had no problems for the first game. However, now when I try to launch the second game, it shows the icon briefly in the dock before leaving it unexpectedly (no error message, nothing... just closes). I tried downloading again and reinstalling, but again it played fine for a few days before the same problem occurred. I did have a character imported from the first game, but I have not altered the downloaded files in any other way. Any advice?
