My Animation playback stops halfway

Question

I have finished my Animation and after exporting it to MOV i played it back on a player and during halfway of the Anmiation it stops (well actually it stops around the 12 minute mark), Even in Flash when i tried previewing my Animation either through Flash itself and HTML, the Animation stops at the same spot, Though playing my Animation through the timeline works fine when i press play. the Animation is 15:59 minutes long with 4 scenes
I dont know what else to do
I have CS6, not sure if it is important to my question
Wish i can send you the flash file so you can see for yourself

Answer 1

I have never run into this problem myself so the first thing I would recommend is the suggested solution in the page I linked.  Create each scene as a separate movie and dynamically load them into a main file as needed.
You might also try.... instead of using 4 scenes, try using 4 movieclips placed along the main timeline one after another (using only 4 frames).  At the end of the each add whatever actionscript you need in order to advance to the next.  I don't know if this still violates the frames issue, but if it does, this could be an nterim step to creating the four separate movies anyways.
