I'm sorry I can't help with your immediate problem, but a warning ....
DON'T use "authorize without an ID"
If you do use it for a very quick test, make sure you don't do anything significant using it.
Any DRM books used under it won't be available on any other machine, and won't work on that machine after any reauthorization.
(If you books aren't DRM, use Calibre instead of ADE)
