Shelfs are always "gone" when I start Adobe Digital Editions to download an EBook

When I start Adobe Digital Auditions all my shelfs on the left side are gone ; I have to create a new shelf to be able to download an Ebook an transfer it to my tolino.

If I don´t create a new shelf, the Ebook is not shown in Adobe Digital Editions an I cannot transfer it to my Ebookreader.

I´m using Version 4.0.2; in 4.0.0 it worked perfectly.

Who can tell me what to do, that my "earlier" regals with the downloaded EBooks are shown again .

I unistalled and installed it about 4 times, nothing changed.

Thanks for your help
