I had the same kind of problems with FLight1. I had to contact them for reinstalling the Cessna Mustang. It happened a couple of times. They had to enable the reinstallation of my legally acquired product on their server for me to be able to reinstall the product and it wasn't instantly. I had to wait the day after contacting them. For this reason I stopped buying products from them. Too bad for CessnaMustang, Qualitywings products, EZCA and the GTN750.
