I asked MAXON about this last week. Their answer is below.
Basically Cineversity access is Subscruption only after the end of the year (as the MSA doesn't exist it cant be renewed). Shame.
"Since Cineversity is tied to the MSA and MAXON's Cinema 4D Subscriptions, your Cineversity expired on the same date.
However, due to the Covid situation, MAXON has decided to give Cineversity subscriptions to all users of Cinema 4D license holders until the end of the year."
