I had an old laptop and I used an eBook from a college SAT prep course named CollegePrepGenius on that computer for a while, however that computer crashed and I was no longer able to use it. After I got a new laptop, I began having trouble accessing the eBook, I kept receiving the error E_LIC_ALREADY_FULFILLED_BY_ANOTHER_USER. After several emails back and forth between the course, they directed me to contact Adobe. I have already tried authorizing the computer with both of the emails I could have possibly used, I have deleted and redownloaded Adobe multiple times, redownloaded the ebook. I am unsure of what to do now. If anyone has any idea why I am receiving this error or how to solve it please inform me.
