Maybe try installing the Direct X that came with the game.... The pink screen means that there is a problem with the Shaders in unity. it might be your GPU but even my Intel Integrated Graphics has no problem with unity.
Taking a little look online Red Moon Entertainment, it seems that your graphics card doesn't support directx 11 (aka. no hardware acceleration) at all, nor does it support any pixel shader support beyond 3.0. So it's looking like that your graphics card is probably too old to run the game properly.

A friend of mine just gave me a graphic card (GTS XFX 8800). I have a ASUS P5B as motherboard, DDR2 ram and 230w PSU. Is this stuff compatible? I tried using that new GPU but when I switch on PC it starts doing noises at very high freq. without stopping (GPU problem). Could it be a PSU problem?
