I'm trying to do this tutorial here useing Iclone 7.1 (not trial) >>   https://youtu.be/9fa7ci0qSX8

I have been stuck for more than an hour trying to get the delayed transition to Rigid Body (Dynamic) to work. 

It says in the timeline that it changes from Frozen to Dynamic ... but when the animation generates the object always stays frozen,
unless I stop playing the timeline and then start playing it again, but it is supposed to change on its own while playing.

Anyone know why this is not behaving as shown in the tutorial video ? 

Thank you
