Error! Check activation

[fcol]

I am trying to borrow an ebook from the library. When I download the book Digital editions gives me the message "Error! Check activation". I checked - It was correct. I tried to erase authorization but got the message "Unable to erase authorization Please try after some time" I tried many times. Then I unistalled and reinstalled Digital Editions. I am getting exactly the same problems and error messages. Please help. I am very frustrated.

	Close all applications.

	In the left pane of the Registry Editor, locate the following registry key: HKEY_CURRENT_USER\Software\Adobe\Adept
	Remove the Adept Folder.
	In the Confirm Key Delete dialog, click OK.
	Close the Registry Editor.
	Open Adobe Digital Editions and reauthorize..

Macintosh:

	quit Adobe Digital Editions.
	Navigate to /Users//Library/Application Support/Adobe/Digital Editions and drag the activation.dat file to the trash.
