7.1 licence eror

What’s the model of your headset? If you have a device from this list, it should be compatible with 7.1 Surround Sound. Also, you can verify if you are activating the code to the correct application. There are users who are trying to establish 7.1 Surround Sound code to THX Spatial Audio and versa. On the other hand, some register the 7.1 Surround Sound code to our legacy software named Surround Sound Pro. Otherwise, you can request a code here. Feel free to send me a PM should you need additional assistance.

I brought a headset today.The model no is: RAZER BLACKSHARK V2 X . I can't verify my code and when I enter my code this error show me "License code is invalid" 

please help me about that

Try request a new code here: https://mysupport.razer.com/app/answers/detail/a_id/6052/kw/activation%20code/

I have the same problem, if I request a new code nothing happens, it just shows a list of your devices, and there is only the old code, which is not valid
