How do I reauthorize my Windows PC after Adobe was upgraded to 4.0?

[annew39684370]

My Windows PC was updated several days ago. Now have 4.0 and cannot download an ePub book from my local library. I can read it on my PC but am trying to download to my Nook. Suspect I need to reauthorize my computer now but do not know how. I have been using 3.0 for several years and downloading to my device with no problem.

Anyone have a solution for this minor but vexing problem?
