NEED HELP WITH EMULATOR ON XBOX

Hey everyone, after digging around on the internet for ages to find no help, I decided to register here and ask for direct help. Here's my issue.

I'm trying to put my Nintendo 64 emulator on my xbox and it's not working out for me. I have it ftp'd over to my e drive with all the files in my emulators folder. I can see it when I open it up and it says launching surreal 64 but THEN it takes me right back to avalaunch. No matter where else I can put it does the same thing. If I change anything around like say putting it elsewhere and trying to launch from XBMC my xbox freezes altogether.

Can someone help me out? I've done this before on a different xbox and not had any issues. Why now? Why won't it work?
