ADE Authorisation does not work (No response)

Hi,

I had ADE on my computer and worked fine.

Accidently removed an ACSM file for an e-book and ADE would not read the file. Reinstalled the ACSM file and still the book errored on ADE

Tried to deauthorise but it would not recognise my log in details so I followed the regedit process and then uninstalled ADE.

I have reinstalled ADE and now when I click "Authorise" nothing happens.

I have tried on two other computers (that never had ADE on them) and I get the same response (or lack of). ALl running W10 Pro (fully updated)

SO I now have ADE but cannot use it or authorise it.

Any help appreciated.
