Export troubles.

I’m working on an animation in Toon Boom Studio 4 and want to export it as a flash file with a preloader. I selected all the necessary options, as the TBS help told me to, but when I try to export the whole flash movie, Toon Boom Studio just crashes. I thought it might be some missing files I deleted accidentally (sounds, photos…), but all was fine there. Then I thought I had no disk space. No problems there either. Then I freaked out and came here. Please, this file is extremely important, has to be published in a week, so please help me out on this one, I’ll be grateful.
