try reinstalling cf and downloading the latest direct x (9.0 or higher), or download the .net framework 3.5 ( or get both) if this still doesn't work try cleaning out your comp and redownloading cf, direct x and the framework stuff. you can get both these products on trusted sites like Free software downloads and software reviews - CNET Download.com (or other free software sites you may know of)
thank me of i helped
