Since the site is down, here is my problem.
I recently started charting a song, and I finished expert drums and guitar. The process was finished and went through Magma well. I put it through audition mode and it said that the file was invalid. I tried to play other songs with audition mode and they worked fine, but this one song didn't. It is an RBA file and I went through my usual precaution with making songs so I don't see why it wouldn't work.
