SW Republic Commando help!?

Hey, i am having a problem withmy Republic Commando game. The HUD (and weapons + character parts) will not show up. You can see the lasers from the blaster but nothing else. I have already tried to re-activate the hud from the options menu and have opened the control panel and tried typing hud (which usually makes it dissapear or re-appear) but none of that has worked so far. Could someone please tell me how to get the HUD back since not having it is really ruining the gaming experiance. Thank you.
