Hamachi Network Client Total Users

On LogMeIn Central under the My Networks portion, I have numerous networks setup.  On each network there is a label that states Multi-Network - X number of users / 999 Clients.  Today it seems I reached 999 clients as I could no longer send a Deployment.  I deleted some older clients and all was good again.

I have two questions.  One, after deleting a bunch of old clients, is there a way to determine how many clients I now have?  I many many devices that are in multiple networks, so are those counted once or however many times they are in a network. 

The second question, is there a way to have more than 999 clients?  I see different subscriptions, but none that show the number of clients.

Thanks in advance.
