December 23, 201312 yr Hello, i want to unregister my serial and reinstall my OS but i can't access to FMC, FSX Closes yourself with PMDG 777 after it loads the flight. I just take a look to manuals and i see this, now i'm planning uninstall T7 first and reinstall OS, can i use my serial again without any problems? I'm afraid because i'm in limit serial activation, maximum 2 times and i used 1, only 1 left. Thank you!
December 23, 201312 yr I have the exact same situation as you, but I don't think you can as reinstalling the OS will clear out any history you had. Rem YangFlying is Fun!
