Export/Test Movie Issues

I'm developing a game on AIR for smartpones and since a few days I have the following problem:

when I hit ctrl + return to test my movie, it won't open and will endless export (the progress bar opens and increases to 100% and this status is for hours). Flash won't create a swf file for me. When I hit publish, my flash crashes completely.

I don't get any error messages.

What I tested so far:

• activated/deactivated movie compression
• activated/deactivated xmp-metadata
• Changed rendermode (without, direct, gpu)
• activated/deactivated jpeg-deblocking
• deleted app.xml file
• increased publish cache size

The only way that the export/publishing works is when I delete elements from my library. But I need the elements. I got 701 elements so far and I need more.

Maybe someone can please help me.

EDIT: It's AIR 3.2

EDIT2:

• Changed save location
• Changed player in publish settings (AIR for Android, AIR 2.6, AIR for iOS, Flash Player 10.2)
• Moved all files to different/new folder

EDIT3: I think it's a problem with the bitmaps. Everytime I restart the fla-file other image previews can't be displayed and when I try to reload the image into the library, flash crashes.

I saved my images again and imported them again, same issue. Sometimes the preview will be displayed and sometimes not.

And when I look through my bitmaps and there are all previews available, flash stops exporting when the RAM usage is at 1,3 GB

And EDIT4 :D

Now I deleted some bitmaps again and it launches the ADL now. But what is the problem with my bitmaps? In Photoshop I hit "save for web" and my other images are not corrupted, but only those "sets" (level 5 and level 6 every time). They are saved as jpg, RGB

It seems that Flash hates much elements in library (or huge filesizes).

After deleting some images from my library and used code to edit/transform/change them in game the problem was solved.
