NEED HELP - Flash crashing

I have a file that, when I go to publish preview it starts to publish the file, then right before the flash movie would come up, Flash just crashes. I’ve tried to publish other Flash files with no problem, so it seems to be file specific. I would have thought it coupld be that the file is corrupted, but I’m able to open it and work in it and save changes with no issues. Only when I go to publish preview does it crash and burn. Any thoughts?
