Using ADE on computer in conjunction with Overdrive on Nook?

I take out books from library which I open in adobe digital editions on my computer and overdrive on my Nook HD.  I like doing both because ade gives page #'s as opposed to # of pages in overdrive on Nook.  I recently had to do a factory re-install of software on my Nook - now, the library no longer recognizes me as the same customer on both devices - anyone have a fix?
