i was playing halo2 for a while (just doing some random glitches) and decided to turn it off, when i went to turn it back on with eject ( my xbox is softmodded) when the disktray went back in it pulled up an error code 21, i tried just leaving the disk in the xbox and hitting power, when it got to the xboxlive screen i logged in and it didnt do anything, i hit start again and it didnt do anything. i have no clue what to do, i found a tutorial on removing xboxlive all togather to fix this problem but i really dont want to do that, anyone know what to do?

umm.. i fixed it with the help of 537h if anyone needs a tut PM me
