Correction to the above comment.
I guess I'm a little brain dead after all this re-imaging. What I meant to say above was the the technical and text books that I was referring to, are not available from Barnes & Noble (not D&B duh!), nor any of their e-book business partners. I would have gladly purchased them from B&N in ePub format.
After putting the Nook Color back to stock condition (1.2.0), I reinstalled the ManualNooter 4-6-16 then immediately attempted the fix recommended above.
In any case, I downloaded the Astro File manager, but since i could not figure out how to obtain superuser status (even with the superuser app) it would not let me remove the two Adobe applications. I could only update them. When they were updated, the banner locked up on the first re-boot. Unlike, the first lock up it displayed the full banner continuously, without completing the boot.
Without source code, it's impossible to tell if there is a bounds problem created by the rooting process, or if this is something else. Someone smarter than I will have to solve the problem.
I think I'm moving on to the less than ideal Kindle Fire, whenever one becomes available. If anyone wants a brand new Nook Color it will show up on e-Bay in a couple of days.
