Please check your firewall.
We've encountered issues with the McAfee Firewall. A deinstallation of the Software and activation of the Windows Firewall and Defender help to fix the problem. Maybe an exception rule for the FlightLog application (ROTAIRGUI.exe) May help too.

There are some known problems with Norton Security. The Software detects the FlightLog as a program which could harm your PC, because it is not a very well-known software. The Norton Security deletes the ROTAIRGUI.exe File. You just have to undo this deletion in the Norton Security program.
