Hi Kerry,
You have obviously worked out that you need to reinstall your previous Licence Key to re-activate your licence with your new software for the remainder of the existing licence period.
Version 20201101 means that the card you have been supplied with has had the newer software - released on 1st November 2020 installed, in place of Version 20200906 previously released on 6th September 2020 - (the version annotation is the issue date running backwards 2020-11-01).
Please feel free to come back if you have any queries about any of the new settings.
Regards
Peter
