I got 'E_ADEPT_ CORE_ KEY_SCRAMBLE' Error for my books

[polo_2951]

When I tried to load my books with acsm file from Google Play Books, it shows 'E_ADEPT_ CORE_ KEY_SCRAMBLE' and I can't load it.

Some of older books could be loaded but most of them doesn't.

I tried to find the way to solve it but I figured no specific answer for it.

Please help.

I got the same error message after purchasing 3 books on Play Store and trying to load them onto my Kobo eReader. Can someone assist us, please?

Same error here. Tried with two PCs and with two ADE installations. Cannot use my Goolge Play books.
