Hi folks. I have an EPUB book that I bought from somewhere several years ago (maybe 2011)? I'm trying to figure out the source so that I can de-drm it properly. I have ruled out Amazon, Barnes & Noble, Apple iBooks and Kobo books. When I try to import it to Adobe Digital Edition, it tells me that "This computer is not authorized to open [book name] because this item is authorized to a vendor ID". But none of the vendors shown look familiar to me.

Any thoughts on how I can track down the source?

Thanks!
