Big black screen on render when adding frames

Hello!

I’m using Animate pro 2 on Windows 7.

At the moment i have added frames on the timeline (from 192 to 264), when i render the animation, everythings fine, i have a big grey screen and in the center my animation, until frame 211, at that moment i have a big black rectangle which have replace the grey + the animation ( = all my screen minus the toolbar).

(I can export the file all fine though, in flash movie) (well minus the sound, but at least i have the end)(but for this, i suspect it may have a connection with the fact that i don’t have quicktime yet)

Thanks in advance for your advices!

It is better have a look at the scene since it is unusual result but it could be a display issue if it shows that way on the screen. If you think it is related to software specific, you better contact support.
