Isn't this like the 4th post your made about Shade-C not working properly? Be careful else the mods might temporarily ban you. Also this isn't the right forum to post this question it.

If it's Shade-C and the screen is messed up then I can only assume that you are trying to apply a Post-Processing effect, but it's gone wrong.

First disable shade-c to see if the level runs correctly. If it does, then you know that the shader effect has been applied incorrectly or variables need tweaking.
