I have RCv4 installed on my second machine using WideFS. I am flying the PMDG 737-900 and everything works fine until I am airborne. Within a minute thereafter, I get the following:Run-time Error 75Radar Contact.rcfv4 module.rcv4codemainThanks,Steve Canham

Hi Steve,That's definitely one for jd!Does it happen on every flight?All the best,John

After it happened the first time I tried the exact same flight again with the same result. When I get some time later today, I will try a different flight. Thanks, Steve

what's the program that saves your .flt every x minutes? are you running it?this means that when (i think it is autosave), kicks off, rc tries to save a .rcd file - but the path to where it is trying to save does not exist, is read only, or not accessiblejd

That was the problem. Autosave is a no-no. Thanks, Steve

Hi Steve,Autosave should work (it does here on a widefs setup).Find the folder where the flights are being saved and make sure that you have enabled the 'Allow network users to change my files' option under Sharing. It could be RC was trying to write it's data file when the flight was being saved but not being allowed to because of that setting.All the best,John
