The PTZ implementation with onvif is new so I have to come back to what might be wrong. However, If you run NCS X and press PTZ buttons and after you release it the cam should stop. Also, not all PTZ cams support this yet.
The only difference between the free and the licensed version is that in the free version cameras number 3 and up have a red banner on top of the image. What might be the problem is that camera information is stored in a new way. For a camera that do not have an image right click on the image and go to Edit video source. All information should be there, but you need to Save it again.
I remember another user with the same problem after an upgrade and that something happened in the installation process.
They solved it by uninstall ncs completely and then install it again and it worked. Do the license information looks like this
Test this and if there still are problem come back here.
