Had crash and need my reg serial again ?

I had a major crash on my computer (HD went U/S) and ended up buying a new HD and re-setting up my Win XP operating system.
On my old HD I had a fully registered, paid for!, version of 4.7 pro.
I have downloaded the version 4.7 but only have 60 days to use it.
Is there any way at all to retrieve my old serial number at all please as I bought the licence for 2 years and I haven’t even had a year out of it yet ?

Any info will be greatly received.
Thanks
Jim B
