I didn't make it!
no crosshair, cant change settings, running on high graphics...im confused
Had the problem myself and started a thread about it. appearently its been deleted or something. But i think you should try medium or low settings. Are you using vista? If so you could try dual booting or hatever its called, it involves using two OSes at once and I have no idea how its done. Try the latest patch or something, for me it started working properly after a while and I dont think I did any of this.
