StepMania 3.9 problem (Tools and Package Exporter)

[ddralen]

Ok, I don't care if it DOESN'T belong here, but I need some help. Ok, I knowingly put an In The Groove 2 theme for StepMania 3.95 into StepMania 3.9 (through the Tools and Package Exporter) and when I opened StepMania, I set it to that theme. So, now whenever I open it, it crashes. And I don't know how to get it off my game. Now remember, I put it in through the TOOLS AND PACKAGES EXPORTER, so I don't know if it's possible to delete it.
