I am hoping that Reality-XP can assist. Today i downloaded the garmin 530 and applied the coupon rxp-athome-2020.cpn which came to $34.97. I paid for it and it appears to have been installed.
I then within the hour downloaded the garmin 430 and this time I downloaded the 50% discount coupons and when attempting to apply the rxp-add-530-to-430-xplane.cpn, it says "the coupon you selected is not a valid coupon file for this transaction".
The site says that this offer is valid until 31 Jan 2021.
I tried to contact reality-xp directly but has brought me to these forums.
Does anyone know why this is happening or if Reality-XP can respond that would be great.
Thank you.
