Aura /Original compatability

I finally broke down and bought a new device a Kobo Aura (on sale at Coles for $109) I am still using my Kobo Original 1st Generation (Not even wifi) with no problems . When I hooked up my new Aura to the computer to charge it started to run through the set up but stopped at the "Connected and Charging" page but would go no further.

Can I run both Kobo's from the same computer or do I have to delete everything associated to the Original before I set-up the Aura .

Any help is appreciated
