landscape is all blacked out.

The landscape other than water is all black after installing my first ad-on plane. any suggestions?

Yes. Uninstall the aircraft and see if it puts your ground textures back to normal.

It would have been helpful had you mentioned which aircraft you installed.

sr71, already uninstalled, still all black.

Not much help I'm afraid. AlphaSim made a payware SR71, additionally there are various freeware ones floating around.

If you want to solve any problems you'll have to be more specific, preferably in your OP.

payware or freeware

where did you get it from

if freeware, state correct file name

inform us of at least your most important computer specs, including which OS

...and last but not least, stay away from anything that bears the name Mark Rooks.
