Yes, luckily I've improved the water abit since that demo. I'm sad the new demo doesn't work for you.
I'll look at the shader now and see if we can make it work.
You would also enjoy the new ship model!
First thing to try is to these cleaned up shader files:

Simply replace the shader files in the Shaders folder.
I have little hope, but you never know.
