Running FS98/FSNav in RadarV4/AdvDiaplay 2.14/FSUIPC 3.53. Fs98 will only allow export to Radar, in old adventure format APL.Need to be able to save in "pln" format to Radarv4. No display on Adv and Radarv4 will not switch off. Any help would be appreciated Get following error message "FSUPC_wait,can"t get FFC to change from 0 always 0" Regards Mike

Hi there,I'm guesssing here but make sure that, on the general options screen of RC, the 'Interact with ai' and 'AI chatter options' are turned off (unchecked). FS98 didn't contain any ai so that may be a source of the problem.I thought that FSNav should be able to export in .pln format whichever version of FS you are using.The .apl format should still work however.If you still have the problem after turning off ai interaction could you confirm that the "FSUPC_wait,can"t get FFC to change from 0 always 0" appears in the advdisplay window and that it is the first thing you see after pressing the 'Start RC' button.All the best,John
