I can see floating objects or mesh cliffs

If you can see floating buildings or objects, either your installation is corrupt or you have a conflicting airport package or addon. 

If you have purchased through Orbx, you can use the 'Verify Files' function to check your installation. Otherwise, manually uninstall and reinstall your product.

If a reinstall, or file verification, did not solve the problem then please remove all 3rd party addons from your simulator. First, add back in the Pilot Plus product and check if you still experience the issue. If the issue is still present please open a support ticket, otherwise continue to re-instate your 3rd party addons to identify which other product conflicts.
