It's a start indeed. Now install calibre, install the Apprentice Alf DeDRM plugin, import the books into calibre, and see if they open in the viewer there. If they do, they're free of DRM. Then just remove the books from ADE (and the "\Documents\My Digital Editions" folder) and never worry about them again. Just make your own backups. (My ADE is completely empty, and I couldn't care less if my Kobo cloud explodes.)
In the same way, see if you can get the other books back...
