You are trying to connect two applications that are working differently. The Gobi E-reader works by opening various e-books, while the Adobe Digital Editions uses an account and digital DRM to open the files. Even if you've had the possibility to open the files, they will be encrypted and the Gobi E-reader will not have the possibility to read them.
Adobe Digital Editions also stores the books in My Documents in a folder with the same name: Adobe Digital Editions. You can try transferring them to Gobi Ereader.
