You may say that I am trying to sell a dead product. Perhaps you are right.
Wait... wait... I never said that. As far as I can see, Blitz3d still does exactly what it says on the tin.
If you buy a car and it works, you don't complain that it doesn't come with wings, right? The car might not fly, but this doesn't mean that the car is useless - it's still a perfectly serviceable car.
Anyway, good luck with your sale. You're going to feel silly in the future, though. Not for trying to sell your B3d license, but for the online sulk. And remember: it's only takes a small step to progress from an online tantrum to a ban-worthy forum meltdown. Might be worth thinking about.
