URGENT - Scenarist does not encode 5.1

[CAMAFE]

Hi all,

I've always encoded only 2.0 and 1.0 on Scenarist Dolby encoder.

Yesterday I need to creat a 5.1 ac3 file, and after loading the 6 wav files, the encoder says:
"Licence keycheck failed in encoding AC-3 5.1 channels."

The Scenarist 2.7 is working properly.
Do I have to input again a key for Dolby encoder ?
Where?


Thanks
Camafe
