Lost cd key

[Bluegrass]

Tried a few tricks and could install halo again but could not play over the net.

Finally did what I should have done in the first place and rang Microsoft in Aust. They are generating a new cd key for me, which should be available within 3 days. Will keep you posted to see if they come through.

They ask for the code on the silver side of the cd.

Thankyou so much everyone for your help.
