Lights and DirectX
 

It's all very good having these weird graphics cards but remember - lights are ran using DirectX. If your DirectX is too old or doesn't support your graphics card then say goodbye to light effects. I believe this is also the case with transparency. Most things to do with special effects use DirectX. Try upgrading to the most recent version of DirectX - it worked for me ages ago.

Yeah I did this, It worked, then it didnt for like 6months then since about 5versions ago lights have worked for me again! Weird x.X
