Edge Animate CC – Exception Error

I recently installed the test version of Edge Animate CC – but it doesn't work.

It starts up with a white screen and a popup showing the remaining days of the trail version, as expected.

After assigning the button continue trail, I may create a new document but can't adjust size or anything else without the error code:

"Edge Animate – Exception: An error occurred. Please save your work and restart Edge Animate" Any ideas? Running on mac osx 10.8.

I already deleted the preference folder – without effect.

Thank you for your help.
