I tried to download a new ebook on my PC and all I get is: E_ADEPT_REQUEST_EXPIRED (with no further information).
I already de- and re-authorized ADE (Version 126.96.36.1991), checked the correct date/time on my PC (though nothing changed since yesterday when it still worked).
any further suggestions?
What you have already done neatly summarizes all my usual answers ....
Is this a bought book or a borrowed one?
If bought, contact the sellers. I don't see why it should ever expire.
If borrowed, see if you can borrow it again.
Thanks for your answer.
However, when downloading a new book ADE worked properly again so only the one bokk from yesterday is somehow "stuck" - and luckily it's only a borrowed one.
