Hey. I have installed the queen (updated install) over a fresh copy of FSX (reinstalled fsx as part of the early tried to fix dll.xml) - every time i try to run the aircrafts, the CRT's will shut off after two minutes or so. I have tried to reinstall the program but it did not help - - also, since the original install (before i reinstalled fsx) it never again asked me to authenticate using my user name and password. I understand this is somehow auth related, but can't seem to sort it out and a reinstall of the program (administrative rights, full access security settings, no firewall etc etc) did not help. help?? thanks again, as always. Kind regards, Daniel.

This sounds like a validation issue. I had the same issue when I downloaded the update. I followed PMDG's instructions and reinstalled it with a new validation and I have not had any more issues with that.Just remember to completely uninstall everything including the add on liveries.Good LuckChuck
