I originally installed ADE and and authorized use without a vendor account or Adobe ID. I had to perform system restore on my laptop and ADE was removed for some reason so I had to reinstall it. This caused me to have to create and Adobe ID. So I registered/created an Adobe ID and password.
Now each time I open ADE and try to read my ebook from the library, I get the error
"The vendor account you entered is not associated with the item you are trying to open. Try again."
When I reinstalled ADE, and I reopened it, the ebook I previously purchased was still there, now I just cannot open it. What do I do?
