I don't know if it is related, but after installing the demo Airac 0609 (for the PMDG 744), Airports and Waypoints information are no longer visible on the navigation display.Anyone has noticed that ?Cheers.

Hi,Same here,Take a look at the forum of NavData : http://forum.navdata.at/Richard Stefan is trying to solve the problem

Gents-there are lots of issues with the new data files in the Demo Airac cycle. Format is the same, but the ordering is off and there are lots of FIX points missing.The files are in text ASCII format, so a simple text comparison will show you what I mean...Best,

The SIDSTARS storage spot is obvious, but where is the AIRAC data stored?I got hit with this problem, and want to back out to an earlier data set, reinstalling it doesn't seem to help. I do have backups though, if I could find where the AIRAC is actually stored ...I looked through the navdata forum, but didn't find anything that related, must have missed it somehow.* Orest

look for the directory FMCWP in your default FS9.. they are under that in NAVDATA

Perfect, thanks! That fixed it.I deleted the lot there, and reinstalled 0608, it did reinstall, whereas it wouldn't before.I have also discovered that quite a lot of the SIDSTARS are corrupted, looks like the .txt files were saved in WordPad format, instead of straight text. Loading them in WordPad and SAVE AS in straight text fixes it, but what a pain.* Orest
