IF you are using ADE 4.0, then you will get an option to erase authorization.
Go to : Help -> Erase authorization
then again you can authorize your computer as: Help ->Authorize computer
thanks Shreya, I've already done it few hundreds times
any other suggestion?
any error you are getting, if yes, please paste the snapshot
The book that you are trying to open was downloaded when ->
1. ADE was authorized without ID ?
2. ADE was authorized with your new adobe id?
At the first time ADE I tried to authorize pc without AdobeID (as that is overkill, another silly account just for one time use)
then I downloaded the book first time,
that didn't work, so I had to create AdobeID, (fist AID was with different email address, which later I corrected, removing and authorizing the pc at each change)
final test that I've done was:
remove ADE from my pc,
remove the ebook from my pc,
authorize with AdobeID (correct email),
download ebook again,
but still have error
You can try one more thing:
"My Digital Editions" folder has multiple copies of the book. You can get rid of all the copies except for the latest downloaded copy (with which you used your new Adobe id)
Launch ADE again
Authorize ADE with id that you used to download the book.
Try to open the book again.
Hope this helps !!
nope, that didn't work either,
I wonder if information about authorized pc is kept on my pc or on Adobe servers.
If that stays on pc I could try to search for registry keys that may cause whole this problem.
One would hope that if Adobe promotes DRM, would also have appropriate documentation and support if theirs product fails.
Now I know, and would promote this idea - do not spent a penny on any epub that has DRM! - not worthed!
