Hey, that actually worked! (Once I inserted an 'm' after 1024, as it gave me an error message...I don't know much about programming, but at least I understand parallel constructions

) And what's weirder—contrary to your warning—it now seems to export fine, even after closing everything and restarting SW without going into the Terminal first and running this command. Huh. Maybe on a Mac these sorts of memory allocation things are "stickier"? Anyway, not going to look this gift horse in the mouth until something else goes screwy, I guess. Thanks for the help!
P.S. Here's the game as it stands:

1) I had downloaded a Dice behavior from SF, but then deleted it. Everything else was mine, I think.
2) I...guess? I'm on a Mac, and have only one user account, so I would assume it's an admin.
3) No, Snow Leopard 10.6.8
4) Sorry...thanks to Epic428, I now can't even recreate the error if I wanted to!
