Two subscriptions needed for ManyCam and ManyCam Lite on ONE computer?

Do I really need two subscriptions for ManyCam and ManyCam Lite on ONE computer?

I just wanted to test ManyCam Lite on my Mac (and I use all my three subscriptions already with ManyCam). So I couldn’t activate ManyCam Lite before not taking on subscription of ManyCam away from another computer! Is this really so?

Since ManyCam for Mac 7.10 ManyCam subscription is device-based and acts globally across all OS users and ManyCam apps. You may need to reactivate your subscription though.
