ART tools. Problem with animation tool

Hello! Ive got some problems with ART tool. Ive wached tutorials for maya ART tool and tryed to repeateverything step-by-ste. However, when the time has come to import created model to animation tool, Ive stucked. Animation tool cant find new models, created for animation… but at the same time I can upload my models to rig editor via Edit exist character. I`ve attached some screenshots to show you what am I talking about.

Aw, by the way, when Ive tryed to work with existing UE models, a lot oferrors occuped the process. Maybe Ive installed ART tools incoorectly? Ive split one of my disk, create empty disk D and put there art tools. Also Ive puttrd them to epic games - 4.12- extras - maya tools/. Also Ive putted userSetup.py file to user - … - my documents - maya -scripts.

Best wishes, Danila.
