I purchased an e-book in March 2017 through my personal email. I downloaded Adobe Digital Edition onto my work computer and read the e-book.
I now downloaded the e-book again onto my personal laptop, and installed Adobe Digital Edition. I created a new Adobe ID and authorised the software. However, when I tried to import the e-book I bought, the software says "Unable to download. Error getting Licence, Licence Server Communication Problem: E_LIC_ALREADY_FULFILLED_BY_ANOTHER_USER". I do not have many email addresses with me. Only email address I could think of were work email and my personal one which purchased the e-book. Both accounts cannot open the e-book due to the error. I was wondering if I opened the book without authrising Adobe ID.
Is there any way to re-gain the e-book I bought? I have a receipt of my purchase with me.
