Cant paste pic from Ai to AE as a mask

ok. so im really stuck here.
I have this picture of a dragons head that i need to paste into After Effects so I opened it into Illustrator as Tutorials shows me how to do. i use livetracing and made it black and white and blured it just a tad.


BUT...

When i try to copy the bloody pic into AE it wont appear as the mask i want it to. (making a logo here with Trapcode 3D stroke here).
So i went back to Ai and tried livetrace and forcing it to create paths and achors and only then it allows me to paste it into AE. and yes i checked the AISC option (or what it name is again).

But when i paste it then into AE i get all the anchors and paths showing=( So my 3D Stroke effect wont work properly.

Why cant i get the picture into AE as the folloowing tutorial shows??? --->http://www.youtube.com/watch?v=Vkm69eiNDCg
