That's what I got... I got it twice in a row, but the first time I noticed that it was trying to load a course that didn't exist... One that I never downloaded and I never heard of... This time, I can't figure out the problem. Help?

EDIT: The stupid smiley is a colon followed by the letter 'o'

I'm no SM debugger, but judging from what you said and what the log says, looks like there's a problem with your Courses folder. If you have room on the hard drive, you can test this without having to "reinstall" Stepmania, per se.

Instead, install it to a different directory (but see the note below this first) and just copy the default Courses folder into your "real" SM folder (replacing the current one), and see if it does anything. If you want to back up your current Courses folder, just copy it into the "fake" SM folder under a different name.

NOTE: Installing the same thing twice in different directories -may- cause a problem. It hasn't when I've done similar tests, but I don't know how Macs work at all so I can't be certain it won't cause a problem for you.

And since you're on a Mac, I know even less about your problem. But while you're waiting for other answers, you could try mine and see what happens; just remember I'm not responsible for anything that may go awry. I've warned you that I don't know what'll happen if you try this in a Mac.

Well, I think it'll work fine... Logic usually works on macs (I'm XP based anyway, so I don't know squat about macs...) and I think that it probably just needs me to go look through it for a moment or 2... I don't even understand the significance of those...

EDIT: Just saved my songs, then reinstalled... Really easy, problem went away. No need to keep my scores... lol. They all sucked anyway.
