How to know license details of current working GSA SER?

I’m moving VPS and the one with the license will expire in 3 days.

I do have access to the working GSA SER tool but I have no idea what the serial key is nor email I used to purchase it. I am 100% sure I have purchase it though since I still have the keys to captcha breaker, indexer and other tools.

I think I purchased using an old email that is now deactivated though. How do I get the license info on the current tool so that I can easily plug that in my new VPS?

I’ve tried HELP -> ABOUT and HELP -> CHANGE LICENSE but doesn’t show anything. The name under the license appears though, just not the serial key.
