License Server Error: E_ADEPT_CORE_KEY_SCRAMBLE

Hello,

I am getting this error when I use ADE to download a book from Google Play. I can't find any information on it, anywhere; and I get bupkis from Google support. As a test, I purchased a book from ebooks.com, and ADE downloaded that book without issue. Thus, I feel the problem is at Google's end - but they're not having it.

If anyone can give me advice, I would appreciate it.

Thanks.
