You probably need to contact AC tech support.
That said, go to the administrative options, practice (licensing info) and check out the data. You might try refreshing info. Your registration code is tied to your practice name. If it is changed in any way, it will not work. Perhaps this was altered in some way???
Anyway, you probably need to contact AC tech support
