I tried to ftp a new copy of ms onto my box, because since I added a new hard drive it never was able to load up the original dash. Which was okay because I always used UnleashX anyway. But then when I restarted I now get an error screen with a 21 in the top left corner. Someone PLEASE help me! I love my xbox and so much money's been dumped into it's hard drive and such. Please tell me there is a way to save it without losing money or replacing my drive!
