error message when I try to update Keynote, Pages, Numbers, Garage Band and iMovie

I just upgraded my iMac to mac OS Sierra, and iTunes 12.5.2 I get an error message when I try to update Keynote, Pages, Numbers, Garage Band and iMovie. It says my Apple ID has been disabled, and there is an error in iTunes. I can easily log into my Apple account with my current ID but cannot update my software.
