Importing Illustrator files

I am using the 15 day trail version on the Mac of ToonBoom Studio.

I few days ago I was able to import an illustrator file (in the .ai format with PDF compatiblity.

Now I am unable to import Illustrator files like before ??

I try to import from the drawing column and select a file, but it looks like it is loading somthing very quick, but nothing is imported.

Has anyone experienced this or someone from Toonboom tech suport can help here.
