Error! check Activation. What to do?

I have downloaded Adobe Digital Edition 4.0 and Help->Authorization Information says my computer is Authorized.

When when I try to download a book and open it the system gives me this Window:Error! Check Activation.

What shall I do in order to make the system running?...

Grateful for answers! Thank you!
