Actors, wardrobe, pose window.

Hello,

I am absolutely newbie in 3D art, Iam using Daz studio only few days but today when I start it my Actors, wardrobe, pose window, it looks like attached picture.

No tabs, no content, anything! (Pose animate and the others tabs works normaly) I tried to find the reason but without succes. Please, can someone give me some advice what happens and how to fix this?

Thank you very much in advance
