John,

Did the program deactivate properly?

In the meantime, I'd send an email to support@pgmusic.com and include the URL of this thread. This will allow Support staff to read about your problem.

In the email, also briefly outline the issue. Something like...

"I deactivated BIAB 2018, performed a clean install over the top of BIAB 2015. When I went to reactivate 2018, I received the message...."

There is a 30-day period in which licensing needs to occur so you'll be able to use BIAB for the moment.

There have been a few instances of activation issues arising on the forum and PG Music have always stepped in and helped out.

When you hear back from PG Music, please add a note to this thread so that others who have a similar problem in the future know a little more about how to resolve it.

Regards,
Noel
