Hey Charles !
Both your Graphics Card itself and the graphics drivers must run on at least OpenGL 2.0.
If the chipset is still on 1.x and not 2.0 capable, you'll need to buy a new graphics card.
If your graphics driver is just not up 2 date, find the driver for your specific OS and graphics card and install it.
Does this make it clearer ? Please let me know if you have more questions !!
Good luck !
Matt
