Licence key damaged message stopping access to my ebooks

[default7y0vjsepir79]

Hello, I am having trouble accessing my ebooks on Adobe Digital Editions, as I keep getting a message "Licence key is damaged" and I am also not able to download any more ebooks into my library.  I have tried contacting Adobe Help and they have just sent me to this Forum.  If anyone can assist me please, I would be hugely grateful!  Many thanks

Having the same issue on a work issued laptop. Looks like can no longer communicate with teh Adobe licensing server, no verification, no read books. Since this last worked on this laptop the only change I am aware of is the introduction of Zscalar as a company standard. This reroutes internet traffic somewhere through some extra checks before hitting the internet proper. I have raised the issue with our internal support team but no joy yet.

Is there by chance a solution to this issue?
