How to know the details of the GSA SER license in operation?

I will move the VPS and the one with the license will expire in 3 days.

I have access to the GSA SER tool in operation, but I have no idea what the serial key is or the email I used to buy it. I am 100% sure that I bought it, since I still have the keys to capture the switch, the indexer and other tools.

I think I bought using an old email that is now disabled. How do I get the license information in the current tool so I can easily plug it into my new VPS?

I have tried HELP -> ABOUT and HELP -> CHANGE LICENSE but it shows nothing. However, the name under the license appears, but not the serial key.
