"Check authorisation" EVERY TIME I download a DRM book even after deleting Adept registry key
A couple of weeks ago ADE stopped opening DRM-free epub3 books (all epub3 format. Epub2 still opened fine). Cf ADE 4.5.10 won't open ANY epub3 files on Windows 8.1 An ADE support tech told me to delete the Adept registry key and re-authorise. I did that, and epub3 DRM-free books now open fine again.
HOWEVER, ever since I deleted the registry key the first time, EVERY SINGLE TIME I try to download a book WITH DRM, I get a "check authorisation" error and have to delete the registry key and re-authorise the pc (using the same account each time).
This is getting seriously old, does anyone have a PERMANENT fix for this problem ??
Using ADE 4.5.10 on windows 8.1.
Thanks in advance if anyone can help.
