The past few days whenever I select an airport in Central or Eastern North America , terrain loads , aircraft loads , after a few seconds there is the spinning icon and down she goes ! Works fine if you go anywhere else , western North America , Europe etc . Happens to stock or addon aircraft , stock scenery , addon scenery . I have tried quite a few things such as removing addon scenery , deleting the FSX.cfg file . I'm thinking it started when there was a Windows update a few days back . Has anyone seen this ?
