Email which sends purchased codes?

Greetings, my computer was stolen and so I was trying to go through my emails to find the code for my commercial licence for gamestudio. I can't find it though, does anybody know what the email is that distributes it (as of late 2015) or at least some keywords I can search to try to find it? Alternatively, I need to contact support but I am having a hard time finding an email or something

I got mine from web at conitec.net.
