Diamond Dimensions crashes?

[Lotsofjoy]

I am so sorry if this isn't the right place to be asking this. if someone can tell me where to go for help with this, I'll go away quietly, and ask there.

My daughters have been playing with a mod called Diamond Dimensions and suddenly, today, it works on one computer, but not the other. It has worked for weeks until just this evening. I tried a bunch of different things suggested in various places here. Other mods seem to work fine and the other daughter is playing it on the other computer as I type this. we have Macs running Mavericks (10.9.1), and I opened and copied the crash report info. But if this isn't the place to ask for help on this, I don't want to post it and get my butt in trouble. I need too much help with this stuff, I can't afford to get in trouble. ;)
