Registration problems

I have a registered CD copy of WD which I initial installed 18 months ago. I have been updating WD when ever a new update becomes available. The new update does not cause any problem with the registration unitl last week when a few of WD’s files were corupted. I reinstalled the original CD version and then tried updating to the current version but it will not recognise the registration now. How do I fix this problem?
