I brought the 747-8 V1 on https://www.aerosoft.com/en/ (A few days before the release of V2 which is annoying because I didn't know about V2 and if I did I would have waited) But how do I get the discount on https://store.x-plane.org if I brought it on another website? (I would be more than happy to send the confirmation emails to prove I own V1)
