A. reg Mountain Lion - I don't know - still X.6.8
B. yes I've updated system several times - resulting in request of Serial No:
• To me there are at least TWO different ones as I upgraded FC in several steps - so there are
- the first legal full version and No: connected to this - and -
- every new up-date has it's No:
And in my case it's been a logic as I can not really follow on which one is requested - so I've got all of them in a list to try when this happens next time.
- It can be the one for the first full version
- the one on the last up-date box
- BUT some times the up-date before this has been the one that works
Never figured out why - still all legally paid for - and still happy up and running.

As Bengt said, it's normal to have to have to enter your FCE serial number when you've upgraded your OS.
A valid SN should not be rejected. Check that zeros are entered as zeros and the letter O is entered as letter O.
Also, l &1 can be confused when entering the number.
As a general rule FCE serial numbers folow a 3 numbers and 3 captial letters pattern.
Mountain Lion is no longer supported by Apple using FCExpress.
I have FCE4 running on M Lion 10.8.3 and it does work.
Users have varying experiences from won't install to mostly works, expect an issue somewhere.
I would suggest a fresh clean install of the OS rather than upgrading over the top of an older version for FCE use.
Having another disc as a boot disc for M Lion can save all your current info on your existing startup disc.
When doing a clean instal of an OS the existing disc will be erased.
Many thanks for your help. I looked back through my files on FCE and found a third Serial Number there which the application accepted. I don't understand why the application suddenly wanted me to re-enter the serial number after successfully using the FCE for so long.
Many thanks much obliged. All is working well.
