You might need the patch the .xbe of the program you're running with a little app called Dexbe (you can d/l at this site). You could try patching it to "Debug" or "Retail" one of those might work since you have a modded Xbox and not a real XDK. Also make sure (w/ Dexbe) that the 64MB RAM limit tag is selected on the .xbe since you Xbox don't have 128MB RAM like a real XDK. These little changes could help you get things running. I own a real Debug Kit my self and I have to say Dexbe is one of the most helpful and used tools that I use, it's an amazing little app.
