I was prompted to update to the latest digital editions on my PC. After updating I cannot access the books. The digital editions opens...but no access to books. Authorisation failure code E_ADEPT_INTERNAL.
I tried to deactivate the authorisation....message saying cannot do so, please try later??..I tried to uninstall and reinstall...same result..failed and same error message.
I need this for my university work as I am doing my research remotely....can any one help please??
