Uninstall and reinstall again? What should I do?
Nowhere I ever said that. I said the error happens because:
- You have the wrong username on SimBrief, and pressed the "Reload" button anyway.
OR
- You don't have an active Flight plan on SimBrief, and pressed the "Reload" button anyway.
As I've said, the next update won't cause these two problems to stop GSX, they will be reported, but they are still errors so, what you need to do is NOT press the Reload button unless your SimBrief username is correct AND you have an active flight plan generated.
