Same problem can't get past loading a flight or activity. Blue bar stops at about 80% and Task Manager shows MSFS not responding. I uninstalled MSFS and did a full reinstall except for Market Place Owned Packages. On my Internet it took 4 X 24 hours to complete. Still having the same problem. Is there anyway of finding out what is causing the issue as there is no message.
