Yeah I thought it may have something to do with my video card, it's an older laptop that does not support 3d capabilities, I figured it may be that, TY for the article

I will try those steps however and see what happens,

It does play other similar games though, I don't know we'll see what happens

Download "DirectX End-User Runtimes"

Open DirectX with 7Zip by right clicking file and open archive, there is 2 versions x86 or x64.
Choose your version and extract it..

Jun2010_d3dx9_43_x86.cab
Jun2010_d3dx9_43_x64.cab

Now extract 'd3dx9_43.dll' from your version and place it in your Cogs game folder
