help needed to backup unreal

[maxzat]

Hi M8´s

I copied the xbox d drive to a folder on my computer using flashFXP. Then i used xisotool to make a iso. I burned it with nero on dvd-r (707 mb). When i put it in the xbox it plays the demo ok, but as soon as it´s starts to load the game, it hangs..

why?

I´m a newbie so i have no experience at all.

Best regards
