Trouble opening ebooks on kobo

My kobo keeps telling me that i'm not authorized to open the ebook. I believe I may have downloaded it under a different Adobe ID. I've now deleted that ID.

I contacted reauthorized my computer, tried using both old and new Adobe IDs, redownloaded ADE.

I'm using a Mac.
