Why cant I? A couple months ago I was able to but now I can't. When I try and start the game up a white screen pops up saying, "the game couldn't start try downloading the game again." Even though its on disc. I also have it downloaded from the market place but it says the same thing. Anyone know whats wrong?

You might want to try the official XBox Forums which may be found at http://www.xbox.com.

Not ever title that was made for the original XBox is actually backwards compatible on the 360. You'll be able to get the support you need as well as a list of what will work and what won't at their official website.

Hope that helps.

Let us know how you get on.

Well its Max Payne 2 so I believe that is compatible. Thanks for the link I think I will also try those forums

Some games are and others aren't. I have no idea what the criteria is either because Halo Combat Evolved works on mine, but some of the later games don't.
