?cannot view DRM protected ebooks in Adobe Digital Edition 4.5 or 3.0

Question

I uninstalled both ADE & re-installed them... and then tried again to view book in ADE and this is the message I get:

Unable to download

Error getting License. License Server Communication Problem:

E_AUTH_BAD_DEVICE_KEY_OR_PKCS12

and this is from books bought from Kobo or borrowed from libraries.

Does anyone have a solution to this?
