Code is already registered for other domain

I have 4 licenses for theme Bridge, already since more than 5 years. Since this week, for 1 of the sites, the license code that I have to enter is refused: Code is already registered for other domain. Is it possible that it is because of earlier versions of the site that are not active anymore? I have no access what so ever to these older sites, they are not active anymore, so I cannot deactivate the license.
