further to my problem, reached max allowed devices in ADE, I reviewed my devices since the beginning of using ADE.
Dec 2010 Pangidital gave it away and bought
April 2011 Sony T1 gave it away and bought
April 2013 Kobo AuraHD still own
Nov 2013 Kobo Glo still own
Dec 2013 Kobo Aura returned 2 days later, not as good as the Glo imo
So I have authorized my computer plus 5 Readers and I have NEVER Erased/Deautorized a Reader's authorization!
Yikes no wonder I'm in a mess
