I've just got my first ereader (Kobo Nia) and I want to set it up with Adobe Digital Editions to read library books on my ereader.
When I connect my Kobo to the computer, I get the screen to connect to PC, and then a screen that mentions that it's connected and charging, and it's stays on that screen
Silly question time: should I just wait until it's finished charging before carrying on the setup?
