I think you don't understand me.
I have won the extra last month. I am programming for another forum user and he wants to use shaders. So he gave me them, and I activated them.
When I forgot to disable them, I got an error and the program abort.
But now, I forgot again to disable it, there was no error - the program runs as it should but without Shader

The Extra Edition does not allow shaders either, but does allow fixed function effects, like the multitexture terrain. Either that's the reason, or you're maybe using a different version of Extra and lite-C?
Does this mean I can use the some shaders?
-->If yes, which?
