Xeon won't start.

Hi I'm having trouble launching Halo in Xeon, I'm not really getting an error but I can't get it to launch Halo. I've tried a NTSC 2004 Halo xbe and a NTSC 2001 Halo xbe and neither work.
I'm running a 64 bit version of Windows 7 and this is my log:

Code:

---

Loading XBE File...
Loading INI file Halo.ini...
Loading input plugin...
Starting emulation...

---

The emulator goes back to the same state it was in when I started it when I try to launch a game. I get an error when I try to launch a Halo 2 xbe as well. Does anyone know what the problem is? Thanks.
