I have tried several times today to start a flight and use activesky (v6) but each time i get the following error message:"main thread process error.....retrying at next interval"What does that mean? Is there something wrong with my program? I used it a few days ago and it worked just fine. HEEELPP.Anthony

Hi,What Build number are you using?Hope this helps,Jimhttp://www.hifisim.com/Active Sky V6 Development TeamActive Sky V6 Proud SupporterHiFi Beta TeamRadar Contact Supporter

I am not sue what you mean by "build"? I am using version 6. Also, i should add that yesterday, i used AFCAD to change the surface of the runway at WSSS from bitumnen to asphalt. Would this have an impact on Activesky?Anthony

I got it. It's build 470.Anthony

Hi,No, the runway would not cause this. Good suggestion though.Install SU4 from the top of this forum and see what happens. If not, then a uninstall/reinstall cycle may be needed.Hope this helps,Jimhttp://www.hifisim.com/Active Sky V6 Development TeamActive Sky V6 Proud SupporterHiFi Beta TeamRadar Contact Supporter
