Thanks for the email closing the case but the issue is not resolved. The page you sent me to: Error messages and troubleshooting tips for activation errors in Adobe Digital Editions does not contain the error code I am getting:

Error getting License. License Server Communication Problem:

W_ADEPT_CORE_EXPIRED

Please explain this error code and how to resolve it.
