Playing halo 2...dirty disk wtf help

Hi everyone,
OK i juss bought halo, and i ftped it to my comp, now ive got all the files, but when i try to make an iso, my iso creator (craxation 4.0) says that it cant access maps\single_player_shared.map because it is in use by the OS??? im totally lost on how my OS would be using this and y i cant access the file. I tried creating iso for like a day straight now, please pleasee help. Any information would be appreciated. THANKS!

 

I got the halo to work

ftp to the xbox
download the entire D folder
look through to your xbox and you harddrive to see if all the files are there and correct sizes
after that delete the intro bik file
use qwick to make the iso
and burn with decrypter
