Hi all,can anybody explain this Error Line: [E] *** LUA Error: ...ht Simulator X\modules\linda/system/handlers-hid.lua:124: attempt to index field '?' (a nil value) I have Linda Ver 1.03FSUIPC 4.721 GreetingsRalf

Check and remove config-hid.lua file from current module configs folder.I.e. FSX/modules/linda-cfg/aircrafts/PMDG 737NGX/config-hid.lua. If it doesn't help, remove FSX/modules/linda-cfg/system/config-hid.lua too.
