No Acoustic Agent in Groove Agent

Hallo,
I got problem. I can see AA is installing during instalation and in Browser of GA but can’t use presets, that is drag and drop to pads, the same from MediaBay tp project (it shows crossed cicle). When I click on preset it appears padlock in front. I can do with such a preset nothing. Is it possible that it happens because of write protected preset? How to solve this problem? Thank you for any help.
