AS3 animation won't play in Captivate 5.5

Hello,

I want to import an animation that combines tweens on the timeline, with animation written in actionscript in a symbol based on the following code:

The AS3 swf plays correclty in Flash PLayer and on the Captivate 5.5 timeline, but does not show up in the preview or when published-neither the tweens or the scripted animation.

Any help would be appreciated!
