Hello,
There are some well known Flash limitations to be aware of for any project implementation. I have listed below just few of these things, but the list can be adjusted (things can be added or removed from the list...I personally hope that many of them to be fixed in the near future, in a way or another and removed from the list

.. while other things will be added as soon as they appear):
1. Flash Document Size limit is max 2880x2880;
2. In Flash 8: bitmap max height is 2048;
3. 256 recursive function call levels;
4. Max 16000 loaded movies within levels;
5. Max characters in a TextField, aprox 63000;
6. Movie Clip drawing limits 1440x1440;
....
As a general rule if, for example, a Movie Clip having 4000 px height isn't showing any longer you will need to split 2 x 2000 px Movie Clips.
There are also various online examples (trial version) available for download in the Scroll Bar / Downloads area you can check, but I guess you have already did so

. If you have the full version just drag&drop the full component instance in your trial example/project and all previous instances will be automatically replaced.
