Retrive GSA Search Engine Ranker Serial

I have purchased GSA Search Engine Ranker some time ago and I have lost my serial and cannot find it in my mailbox either - how can I retrieve it?

I have resent the licenses to your email.

Oh lol, I never thought you would respond back

Thanks!

PS: Pretty nice piece of a software you did here as I see it's still being used after 10+ years. I bet you did lots of money from it
What other cool projects have you done recently? Anything AI related ?
I bet your github account it's a nice place to look around but I cannot find anything with your name  

Well to be honest, we are not making a lot money. We do not advertised it and the low price (it's a life time license with free updates) is also not helping to make money. However, I like coding on it and Im always open for new ideas. 

It's a joy/fun project that pays the bills but it is not paying m rent or making us rich for sure.

AI is a hype...however I see it's potential in many fields. Text generation e.g. and there we have it added to many tools already (API access to all kinds of services).
