I need OpenGL?

[Guest]

I want to play this game, it's a 2D game that can run on DX5, DX9 or OpenGL. It runs with a slow framerate on the DX5 and sometimes freezes on the DX9, but the OpenGL option is unavailable to me on this computer...I was wondering if anyone knew how I could make it available or explain it a little because I really don't have much idea at all of what I'm talking about. Thanks in advance.

Can you give us some info on the PC?
CPU, motherboard, graphics card, OS?

I could be a graphics card issue, as in the GPU doesn't do OpenGL.
