Video Enhance AI + Nvidia GeForce GTX 980 TI GPU


I have Intel i9 7990X CPU and Nvidia GeForce GTX 980 TI GPU.
I have Game Driver installed on my Windows 10 64 system.
I see that Nvidia doesn`t support 9 series for Studio drivers.

When I try to run upscale processing using GPU I got the error regarding the model.
So, I am not able to use GPU.
Initially I created an account for trial version, after that I purchased license, but I still not able to run processing using GPU. I am only able to run upscaling process using CPU.

Is it something wrong with my account which was initially trial one?
Or maybe there is no support for 980 TI graphics card.
Please help me
