For the first time after several months of usage of my PMDG 600-900 series, I experienced CTD when loading any of them. The sequence is as follows:- Load FS9 with default Cessna- Select PMDG 737 (any model)- The navdata loads- Black screen- crash...All my other add-ons work flawlessly, I have not touched or changed anything at all to the PMDG files.I have done a search and found two similar topics, tried Anthony's suggestion, to no avail. Any help would be appreciated please.Many thanks.

It's really easy to uninstall and reinstall PMDG, using the Uninstall Utility on their web site. If you can't figure out another reason why this is happening, at least you can eliminate a corrupt file.
