Simple movie texture plugin with RawImage issue

Hi:)
I’m trying to dislay a movie on a RawImage component with no luck using the simple movie texture webgl plugin.
A guy in the following post ( How to use a RawImage with Simple MovieTextures for Unity WebGL - Questions & Answers - Unity Discussions) claims that he found a solution but it doesnt work for me either…
Your help is greatly appreciated:)
Thanks;)

I’ll just mention that when using a cube with a mesh renderer , it works (as in the sample scene that comes with the plugin)

Anyone? I’m really stuck here:(

The solution for me was to download version 5.3.6f1. Anything after that gave me problems.
