Scaleform no visual issue

So there is a nice solution I want to use: [Release] Generic DUI 2d/3d renderer

I made it the client script with C#. The problem is that only sound is playing with no visual and I cannot figure out why that is.

Is anyone that has solved this problem willing to share their wisdom with me?
Client.cs (2.9 KB)

The script I attached is the JS example I converted to C#.
