I've now got around to creating a simplistic rendering system with OpenGL, however while testing I'm encountering an access violation exception which occurs when I try to call glGenBuffers(1, &m_ElementBuffer);.

My Renderer::Init function has this in it:
Code :
		fprintf(stderr, "GLFW failed to init, CRITICAL ERROR!\n");
		return false;//Have to back out due to severity of error
	glfwOpenWindowHint(GLFW_FSAA_SAMPLES, 4);
	glfwOpenWindowHint(GLFW_OPENGL_VERSION_MAJOR, 3);
	glfwOpenWindowHint(GLFW_OPENGL_VERSION_MINOR, 3);
	if(!glfwOpenWindow(int(m_Dimensions.x), int(m_Dimensions.y), 0,0,0,0, 32,0,GLFW_WINDOW))
		fprintf(stderr, "GLFW Open Window failed, aborting...\n");
		return false;
	glewExperimental = true;
	if(glewInit() != GLEW_OK)
		fprintf(stderr, "Glew failed to init \n");
		return false;
I then go on to parse an xml file to further initialization.

The problem I'm getting is when I call a sceneNodes init function which then calls its renderObjects init function which creates the buffers and all OpenGL related 'stuff' for that object. I am fairly sure that I am calling this after glewInit and have double checked numerous times although I will check it when I come back to this after a break away from the computer. I figure that something has gone wrong with glewinit since in my watch list, when I debug, it says that glGenBuffers is undefined however it also says this about glClear() which executes fine.

I'm sure it's something obvious that I may pick up straight away when I come back to it, but for the moment I am stumped and would appreciate any suggestions.

Realized some extra information might be needed, I using an AMD Radeon HD7850 Core Edition for XFX, I have used this function successfully in another project without any issues and glGetString(GL_VERSION) returns "3.3.12002 Core Profile Context"
