As the heade says my cockpit sounds, safeties,clicks have gone dead. Even after loading the 727 twice.

I had a computer crash with my old computer and it died ( Fried) I purchased a new/used machine with a bit more power.
Today reinstalling the 727 the installer doesn't ask for the ord. number. I have the installer saved on disc and on Memory sticks. I realized it was installing anyway and it did put the plane into my FSX installation under my C:\ But the captainsim folder that installs directly into the C wasn't there and it contains the ACE,sound Sound.cfg,Flights etc... I tried once more and it did install the file, but still no cockpit sounds???? Have I forgotten something? Or what do you advice?
The installer runs but doesn't ask for the Order No.?
