Reinstalling OS and about my serial..

[madcuzbad 0]

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!

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.

I must reinstall my OS to solve this issue..

Did reinstalling the OS solve the issue for you?
