There´s not any official info about opened Cineversity service till the end of year for all perpetual users.
They hold data (related to licence) of all users (perpetual/subscribers), so they know in any time if you have active licence/Cineversity service or not.
Only what is clear for me is MSA users with finished contract has not access to Cineversity...
Maybe Rick could clarify things...
....
I don´t want to risk they turn off Cineversity for you (as you currently have it) if I ask for Cineversity too and then I´ll stay bad guy for you :-)
