do you have an ORIGINAL halo pc installation and an ORIGINAL hpc disk?
did you buy it from a store? was it sealed new when you got it?
if one or more of these are false, then someone else may be using the same copy as you, leading to complications. if you are using a nocd hack that explains it. if you arent using the original disk to play that explains it too.
