How to change maximum number of AutoMate Enterprise Server Agent to AutoMate Enterprise Server?

I know we have purchased 2 copy of AutoMate Enterprise Server and 10 copy of AutoMate Enterprise Server Agent.

We are running 1 AutoMate Enterprise Server at the moment with 6 AutoMate Enterprise Server Agents connected.

I'd like to add one more AutoMate Enterprise Server Agents but I can't add with fallow message.

"AutoMate Agent 11 cannot connect because maximum number of licenses has reached on X.X.X.X"  (image attached)

How can I add another AutoMate Enterprise Server Agent?

 Hello,

I would suggest that you speak with your Account Manager, you will need to purchase additional agent licenses in order to fill your request.
