First of all, congratulations to the RC team for this great add-on. I did my first flights meanwhile, and everything worked just as it should (or even better :-))Today I remembered that I did not rebuild the scenery db after installation. After starting the process, I immediately recognized that the numbers of airports and runways found so far stayed very low (I did not note it down, but both numbers never reached 100). When the process was finished (no errors reported), I had to realize that these numbers had been real, so my a4.csv and r4.csv file had become very small, and loading a flightplan into RC resulted in "runtime error 53" messages.After already 2 or 3 users have reported similar problems here on the forum, perhaps it would be a good idea to check the rebuild process again.My problem has been solved by reinstalling RC, so no need for urgent help...Nevertheless, thank you for this marvellous software!Kurt

makerwys, that does all the scenery reading, and building of databases is a pete dowson creation.i will forward your message to him, and see if he wants to look at anything from your configuration. it works zillions of other places.jd

Hi Kurt,Could you also go to your main FS folder and find two files, scenery.cfg and runways.txt If you could zip these up and send a copy to [email protected] with a note asking him to forward them to me (John Burgess) it should enable me to see what happened.All the best,John
