paid account not allowing new machines

I have a paid account
I am trying to install host on a machine to be able to connect to it when needed.
I am getting a message stating I have reached my limit.
 
Here is the message:
Install limit reached, withg your edition you may have Teamviewer only on a limited number of devices which you have now reached. Please either deactivate an existing install in your account settings or upgrade to a higher edition
 
I thought I could manage an unlimited number of machines?
Did I do something wrong?
