Adobe digital editions opens but does not work

When I open adope digital editions, it is blank. I can use the menu buttons but I can not open anything. I can't see the buttons I should see. I add a picture of how the digital editions looks like. When I started to use it last september, it first worked fine. After about two months it just stopped working, and has been like this ever since. I have tried to uninstall and reinstall, no change. I downloaded older versions, they look all right, I can add a book but I can't read it. 

Any ideas what I could do?

Edit. Renaming the ADE file I get it look like as it should be but when I add a book in it, it stops working. It does not respond. I can close it and reopen it but book is then gone. This happens every time.
