Can download books on Digital Editions 4.5 but can't read the books

[bookbuff31]

I had downloaded Digital Editions 4.5 and it was working well for several weeks to download library books.  But now after a recent digital edition crash - I can download the books, it gets fulfilled but I can't read the book as nothing happens when I click on the book  and adobe digital editions doesn't synch with the previous books that I've downloaded.

Do you used which operating system?

Has you try right click and choose run as admin?
