Good news. I have created a store which will send you keys automatically. To purchase these keys head over to https://store.heronstudio.net/index.php?route=product/product&path=59&product_id=50 . Once the payment goes through, you will receive your key automatically
You can still support this project by donating. Thank you so much to everyone that donated and thank you to everyone that is using LukeAirTool
