Whenever I try to open the .fla files to run the tutorial flash documents that are in the start_files directory for Macromedia Flash MX Professional 2004, it gives me a Unexpected file format error message, and fails to load. Anyone have an idea of whats wrong? Thanks..

usually it happens with them, who use patched flash..
buy flash - it's only right and gentleman's way. or use another crack (;

Yo, The reason is like the guy before me said, its because your using the cracked exe patch, a remedy to your problem would be to either buy flash so macromedia can continue to make great products, or you could use the dll crack instead. but if you do that you will still have to reinstall flash. hope that helps.
