I read DRM'd books on my Vox using Aldiko and had no problem authorising DRM books with my ADE username and password in the Settings.
So you may have too many devices authorized?
Here is info from the ADE forum about how to reset the number of devices; it basically involves deleting ADE from your computer, clearing all the ADE folders and then re-installing to start your device count from zero again.
Quote from the forum:
As for the number of devices.... I think ADE's statement here is
misleading, but the crux if the issue is how that device count is kept.
It's not reset if you drop a device or reinstall ADE, which I think it
should be. In order to clean it out, you can uninstall the software on your
Windows PC, and delete any remaining folders under Adobe Digital Editions,
then EMPTY THE TRASH. That cleans out your registry as well as the hard
disk of any files that Adobe might look for when it's installing itself.
(Technically, it appears ADE checks for previous versions and if it finds
one, then it preserves certain keyfiles including the one that holds the
attached device count).

If you go for the deletion route, you should go into your Digital Editions
folder and move all of the books, pdf's, etc. that are in there to another
folder somewhere else. You can move them back after reinstalling ADE, but
you will have to add them back to the library one at a time
