I can't choose custom render mod for Tiberium Sun launcher (Singleplayer)!

[Pjotr Vyglidalovic]

I just download Tiberian Sun online and Tiberian Sun and singleplayer. But there was one problem. When i start the Tiberian Sun singleplayer on Tiberian Sun launcher, i see the black screen. But game was ok. I right now know, i have to select another render mod. I go to setting and i choose render mod. But i can't. And why? Because the ddraw.dll ist used by another aplication. This will hapend when i choose the render mod and i select ok. It will say: ''access to way C:/Westwood/SUN/ddraw.dll was denied'' Please help! I almost write it enywhere.

Make sure the game is not running in the background, open up the task manager and kill the tiberian sun game.exe process. You can also restart your computer if you don't know how to kill it
