Upgrade Download

I upgraded last year from Elements 9 to 14.  It upgraded digitally as an offer when I fired up Elements 9.  I paid for the upgrade and it downloaded.

Now after a complete reinstall of Windows 10 I can't get my 14 upgrade.

Can anyone tell me how I do this plse?  I still have files from 14 on my computer and one was setup but it's asking me for an I.D.  When I put my adobe I.D. in it said it wasn't correct.  I tried several times with the same result.  This was despite using the same I.D. on the adobe website which worked a few minutes previous.

As far as I know I didn't get a licence key for the upgrade as it just downloaded straight from elements 9.

Can anyone tell me how to get my upgrade reinstalled please?

Thanks.
