Vide0guard unique EMM's were not working in oscam between range 8830 - 8962.
If you are using oscam to read your 0963 card (or any other Vide0guard card) on your server and your oscam version falls within this range, you will not be able to update your card.
I am not 100% sure if cards updated using dvbapi were affected but anyone updating through cccam protocol will not be updated.
I should have posted this a long time ago as I feel it might be responsible for a lot of the problems with 0963 cards updating..
Can everybody creating backup images please make sure to upgrade (or downgrade) to a working version of oscam.
(For me personally 8825 was the last stable working version before the Fix in 8962)
