I have the same problem. I just bought 2 books from Kobo and there is NO way I can find a usable copy of the books on my pc. I have ADE and the kobo app, where the books are thanks to a previous post here and of course Calibre, but I cannot load anything anywhere. Just spent hours trying everything in creation but no joy
. Cannot even find the plug-ins for Calibre. I do not have the latest Calibre, because I'm still using win7.
