I am having almost the same problem. I purchased the licence and after purchased nothing happened.Then i decided to try it a 2nd and third time and it gave me a message that the itam was already in purchase process. In the end done 3 payments and P3D is still not activated. Update: After restoring from the server Prepar3d is now activated but when installing textures it said that it cannot install until a valid licence key is installed. am i missing a step?
