From free license to premium

Hi all.

I installed TV 12 (my Premium lic. is for version 12).

I logged with my account but i get always the error "your free license is expired" and i can't connect to PC's i see in my list.

I cheched on the web console and it says my license is Premium.

How can i remove "free license" from client and install "premium license"?

 

Thanks in advance
