Black screens (PFD/MFD) on H850XP FSX/P3D

Q: The H850 XP has no screens (PFD/MFD). Everything is completely black, and when clicking on the 2D panel, it is just a grey rectangle.

A: Please follow these steps:

- Go to the GAUGES folder on the simulator´s root folder, there is a file named PROLINE21.CAB or CARPROLINE21.CAB, delete it.
- Run the H850 XP uninstaller.
- Install it again.

This should solve the problem.
