MAMP Pro license record

I purchased a license for MAMP Pro and copy/pasted the license on the webpage when I ordered it. But there is no record of the license key on the invoice or on when I login to their support system.. I am retiring this computer and transferring my work to a new computer so I am trying to find my license so I can reinstall MAMP on the new computer. I've looked through the ~/Library/Application Support folder and /Applications/MAMP Pro/ but I can not find it in a plist file either. Does anyone know where this is stored or where I can find it? I've already submitted a support ticket but figured I'd see if someone knows rather than waiting around for them to get back to me.
