There maybe a problem with Cycle 0906.I installed cycle 0906 and when I go to load a PMDG aircraft, I get a CTD.When I reinstalled cycle 0905, everything works without a CTD.

Which aircraft?Maybe a bad download? I'm running 0906 as well as hundreds of others and this is the first comment. I'm not sure how a bad navdata could cause a problem but you could try a couple of things: Open the navdata files with any text editor to verify the files are readable, and then open a few sidstar files for the same reason. Try re-downloading the zip file (navigraph allows multiple downloads in each cycle for the same cost).

Hi,There is a problem with the orginal 0906. Go back to navigraph and you will see the new version: 0906 V3.With this one everything will work fine.AlainV

No trouble here with 0906.
