Is solved the problem:
i have deleted these files (changed the location) from FTX Global for LDSP :
ADE_FTX_FTXG_LDSP.BGL
ADE_FTX_FTXG_LDSP_CVX.bgl
ADE_FTX_FTXG_LDSP_GP.bgl
ADE_FTX_FTXG_LDSP_OBJ.BGL
ADE_FTX_FTXG_LDSP_STATIC_AIRCRAFT.BGL
I have installed the new scenery via Orbx ... but in P3d4.5 there is another scenery for Split active ( i think a default scenery)..
but know there are two towers and static aircrafts (from defaukl scenery)
HOW do i uninstall the default scenery?
