Guess, before we can help you, we need to ask a few questions..
What version of fsx?
Did you add the required orbx regions?
Did you install tongass from the exe install?
Did you add rtmm from the master zip?
Did you add the scenery entries for rtmm and ensure that, as well as the tongas entries, are sequenced correctly via
the scenery.cfg and also set up the insertion points inside ftx central ? (Instructions to do this is in the rtmm install docs)
Once all of the above is correctly setup I suspected that it
will cure your problems.
Follow the rtmm instructions/install file step by step.. and that should correct any issues.
