It would help to see the first sixty lines of the crash log; the above error message is usually accompanied by a log showing the reason for the crash. So we can only guess.
If the crash happens, when you are moving around audio files, the reason may be that you are having a corrupted aidio file in your GarageBand project.
Select your project in the Finder window and ctrl-click the project file. In the pop-up window select "Show Package Contents". Now you can look inside the package and open the "Media" folder. There you should find your audio files. Copy them to the Desktop and open them in another application to check, if one of them cannot be played properly.

Thank you so much for all the text. : )
I don't actually have any audio in the project because it keeps crashing and erasing all of my data. I'm only using Apple Loops, anyway. All I have in the project is a movie clip.

It doesn't. If this occurs in Mountain Lion only, I know I'm certainly not running Mountain Lion. All it says after the crash is Ignore, Send Report or Reopen.
