I've recently written a simple program that uses OpenGL shaders, which works fine on my computer. (Windows 7, HTI Mobility Radeon HD 5800)

However, when I try it out on a differnt computer (Windows 7, Nvidia GeForce 220), the shader gives an error that I am haveing trouble understanding.

(apologies, for some reason, "insert code snipet" seems to work for me as well as this shader does, (that is, not at all))

Error:

Here is the vertex shader I think it is erroring on. I use a couple shaders, But I am fairly sure this is the one.

Also, I know it is not good practice to compute the matrix inside the shader. I need to refractor my code for OpenGL 4.1 anyway:

vertex Shader:

uniform float height;
uniform float width;

void main(void)
{
vec4 rowA=vec4(2.0/width, 0.0, 0.0, 0.0);
vec4 rowB=vec4(0.0, -2.0/height,0.0, 0.0);
vec4 rowC=vec4(0.0, 0.0, -1.0, 0.0);
vec4 rowD=vec4(-1.0, 1.0, 0.0, 1.0);
mat4 Ortho= mat4(rowA, rowB, rowC, rowD);

gl_Position=Ortho*gl_ModelViewMatrix*gl_Vertex;
gl_TexCoord[0]=gl_MultiTexCoord0;
}
