Basically, what I only modified in the .fla file is the library. I created a new folder in the library and I moved all of the bitmap images into it. Also, I edited something from the preloader in the game... I saved the file, then whenever I open it, the error happens.
Also, the same error happens after I have edited the properties of the image, I imported new images and saved. Whenever I open the file, the error happens. How can I avoid this from happening?
Also, what are the possible effects of this error to the file? Because I cant find anything wrong with the file except for that error.
When this happens, it usually means one of your bitmaps is corrupted. \
If so, this is the work around:
Go through librabry, selecting each bitmap item in turn (don't double click)
until you see one that shows an error in the library preview area.
Delete that form the library and re-save.
You then will need to find that source image again and re-import it.
