I bought the crj 500/700 directly at Aerosoft. Right now, Contrail has all crjs including the upgrade in their sale. The Contrail Desktop App did recognize my crj 500/700 installation but I am still not able to click the Buy button.
So, I guess that I will only be allowed to upgrade the crj in Aerosoft’s webstore as this is the shop I bought the base package at?
