Error Message when trying to open downloaded books

[AdelynC]

This message pops up when I try to open books I've downloaded:  Error getting license - Server communication problem:  E_ADEPT_RQUEST_EXPIRED.  Please tell me how to fix this.

What files are these?

What is your device or operating system?

Is it connected to the Internet?

Thanks for your response.  They are e-books I've gotten over the internet from my library.  I have an iMAC with Snow Leopard.  I have constant trouble with the Adobe Reader.
