FLA file not exporting/test/publishing to SWF?

Im working on my website which was from a template. Ive gotten pretty far and all of a sudden my FLA file isnt exporting to a SWF file. It doesnt let me test the movie either, it shows the progress bar then does nothing. Similar to this guys problem on another forum: http://forums.tizag.com/showthread.php?p=72453


It shows the file in the folder for a split second then disappears. I really dont know what to do and I dont want to continue working on the file if theres a problem.

Help would be appreciative.
