As long as you used the same AdobeId you should be fine. If you did use the same AdobeID, are you sure your new computer is seeing the nook (does it show up as a drive)?
Jim, Thanks for your response. Yes, I have used the same Adobe ID. Here's the current status per your question:
1. With ADE active and my Nook hooked up, my Nook appears as a "device" on the "Devices and Printers" window (in Windows 7). The Nook's property status reports "This device is working properly".
2. In the "Computer" window, the Nook does NOT appear as a drive. The Nook also does NOT appear in the "Safely Remove Hardware & Eject Media" window when I remove it from the computer.
What action should I take? Thanks very much for your assistance.
ADE won't see your Nook, unless the computer sees it as a drive. So your quest is to get it to see it as a drive.
I would try using different USB ports (if you are hooking it up to a hub, try hooking it up to a different USB port), and if you try using a different cable (one from your phone if it will work, for instance).
Thank you, Jim and Frustrated, for your assistance. We have solved the problem (with the additional help of the Barnes and Noble ColorNook support staff). Turns out that when we installed Nook on my new computer the drivers did not properly download or install. We uninstalled the old drivers and the Nook folks downloaded new ones. Now everything is working great. Thanks again for your help.
