Can not activate Nitro Pro 12

[Camille Seabourn]

Hello - for some reason my Nitro Pro 12 was not working and it asked me to purchase a subscription or activate my subscription.  I tried to re-activate my subscription using my Serial Number.  As instructed, I first de-activated my subscription (although it was showing that it was not activated) and I uninstalled the program, re-installed it and then tried to activate my subscription.  It gave me Error 24.  I checked my license and it showed NO active licenses but 2 unactive licenses.  How do I rectify this issue?
