You must be using an HTML5 Canvas doctye in Flash Pro where you see these options as disabled. This is because of some limitations in the CreateJS export or browser support for some of these features.
If you create a regular AS3 doctype(for Flash), it'll have all of these options enabled.
There are no limitations in terms of features in the trial version and full version of Flash Pro CC, apart from the time limit ofcourse.
Let me know if you still face any issues.
Thanks, it worked!
I have one more question. Is it possible to convert an HTML5 canvas to an AS3 one, or do I have to copy and paste all the frames over everytime?
You'll have to select all the layers, right click -> Copy Layers, then Paste layers in the new document.
There is a script that essentially does the same thing as above for AS3 -> HTML5 Canvas document conversion. (under commands menu)
Thanks for the help! Everything's working now.
