Been there, done that, bought the t-shirt.

It works fine for my 505 and my Sony elibrary works fine for the 600 so it must be updated. I have not been able to determine which version of ADE I currently have but tried downloading the newest version from 2 different browsers and couldn't get it to download.
I was thinking of uninstalling the current version that is on the PC, try to download the updated version and then see if I can authorize the 600 but what I would prefer doing is adding the epub books directly to the Sony library. Is that possible?
Thanks!
