I purchased the level 2 GSX and downloaded the full version wich includes level 1&2, installed successfully and showed regestration active, however when I started my sim at KSFO the GSX menu did not give the usual operation options but it showed only ( 0 parking available ), I restarted GSX and restarted airport cache but still does not work. Moved to KIAD airport then the menu worked and I did fly to KJFK however I got an error message at the final approach and the KJFK airport did not load nor the GSX menu did not show options. There is something wrong any ideas what might be wrong?
