Question for you CoD gurus... So I have CoD on two computers, don't ask

, I downloaded the patch and it installed just fine on comp 1 (about a week ago). I'm now installing on comp 2 and the zip file only contains .ogg files (I remember that on comp 1 the zip contained a number of sub folders.) is it possible that tge download has changed? Or have I missed somthing painfully obvious?
Thanks dudes
