RenderTexture not working in standalone??

Hi. I am creating a mini-map for a game. Everything works just fine in Editor. Using Unity Pro 4.2.1f4.

But when i build it (standalone x86) the map is blank.

I assigned the renderTexture in the inspector before. same goes when i try to create it by Javascript:

var renTex : RenderTexture;
function Start() {
     renTex = new RenderTexture(256, 256, 16);
     renTex.Create();
     Debug.Log(renTex.isCreated());
     camera.targetTexture = renTex;
}

it always returns false IN STANDALONE ONLY.

The thing is, I am using Windows 8, and all previous builds from Windows 7 work just fine with renderTextures. (this is not my first time doing maps.)

Did i do something wrong?? Pls help me…Below are some screenshots from my game…

Thank you.

Tried 24 for your depth buffer size?

yes. I tried all the settings with the same result.

Is there anything about the rendertexture mentioned in your output log file?

no.
