Same issue. After installing FSUIPC update I started receiving FSUIPC message when open axes setup "FSUIPC is not connected to FS" or similar. Since that, FSLTL will only report "simconnection failed" I`m really frustrated about. FSUIPC is necesary for a lot of ADDONS and peripheral and many other stoff, but unfortunetly gives a lot of troubles. Any fixes? any idea? Thanks in advance!
