bontegames We also contacted them about the commercial version, and a few days later they requested we send them a purchase order listing the seats/tiers we wanted to purchase. A little while after that they sent us a temporary licensing file we could use with a version of AIR 33.
It sounds like their newest download of AIR 33 has systems in place now to check in with their servers for licensing (to decide if it should add the splash screen or not during compiling), so eventually we should be able to sign up and pay on the website, but I'm not sure what the timeline is looking like for that.
