I downloaded ADE and upon install I first decided not to activate it.
I bought an ebook and put it in ADE and it read fine with no problems.
Then I thought it might be usefull to have it on my laptop as wel, so I decided to activate my version of ADE.
The problem is that the book no longer works at all.
not on my laptop and not on my normal computer.
ADE says that an other user has the license to the book.
But the only thing I did was activate my ADE.
how do I fix this?
Thanks in advance
When you authorized you replaced the existing activation on your machine - essentially switching the users. There is no way to get back the old account because it was anonymous. The only fix would be to ask wherever you bought the book from for a new download link.
