Recently FSDT has released a major update to GSX which has affected Flightbeam products. It's our understanding that the problem is GSX isn't able to read the pre-configured GSX ini files. Please don't email support, there is nothing we can do about this GSX issue. Some solutions: - Simply delete the GSX ini file in the scenery folder of Flightbeam airports- Contact FSDT Support- Visit the FSDT Support forum about this issue: https://www.fsdreamteam.com/forum/index.php/topic,26716.0.html
