The system ID should either be in your avid account on the top of the page or in your avid appman (application manager) so look and see if your see the system ID there anywhere.

And all the PT10 updates were full installers, no one were anything like half updates, all of them from 10.0.0 were full i stallers so thats not it.

If this prolongs anyfurther and you cant find system OD and not registered I will have to escalate this issue and see if A id can help as I cant see your account info etc.
