Good morning. After several attempts of uninstalling and reinstalling the program, I still get the same outcome.
I can update all simulator base packages without any issue, however, when I try to update add-on packages like the CRJ 550/700 or the PMDG 737-800/&&&-300ER, the program freezes and locks up
Try rebooting. I think something gets stuck with the PMDG update. It affected the IFly update as well. After rebooting PMDG showed the install button and then I was able to do the IFly plane
Okay, this is strange. For Aersoft CRJ, try to delete the Aerosoft-CRJ\Data\NavData folder in Community. For PMDG 738-800 pmdg-aircraft-738\\Config\\NavData and pmdg-aircraft-738\\Config\\SidStars folders.
