Lost serial

[themacawguy]

is there a way u can find out ur serial if u lost the case please help

[Jay]

try to contact microsoft. They'll probably need your proof of purchase.

You could use a crack or a serial code off of the net.

Can we all say, "Banned"?

I think I'm going to make a thread about getting your cd-key back.

[FReAK]

well u should have a service number that is somwhere in halo cus i sawq it when i installed it... try reinstalling it [if its currently installed] on your comp and then if it doesnt ask for a cd key then before you finish a number on the right side of the box should pop up. write that down and call bungie and give thenm that # and theyld prolly give u ur cd key. If not just give them the proof of purchase like that one othe dude said.
