I think the most likely reason Infopop doesn't allow us access to their license database is the privacy of it's customers. Though we all like to think of ourselves as honest, who's to say what may happen if a warez-kiddie posing as a developer suddently gets access to 200,000+ other license numbers... See?
It's been suggested that Infopop (or one of our developers) create a way to query the license database without us ever having actual access to it- we just place a script on our page that checks it and we personally never have anything to do with it. But I think that idea was shot down as well, for reasons I don't remember. Probably cuz it would be too easy to alter...
At any rate, I'm glad your problem was resolved.
