My first post here in years! I must say, it feels good to be back. I haven't played SC4 since getting a Mac way back in 2009, and I've only ever played on the PC version. The problem I'm running into is with custom regions - when I open the region dialogue box with ctrl+alt+shift+r to load a grayscale, the box opens, but I can't navigate to anything. It won't show any files or directories, and where files should be there's only a little black box that makes the game crash when clicked repeatedly. Any ideas?
