Mt. Rainier just like ALL other Packet Writing programs is problematic from the get-go and just doesnâ€™t work. The fact that you are having difficulty obtaining definitive information on Mt. Rainier is an indicator that Mt. Rainier is defective by design and doesn’t work. If it worked as advertised it would be readily available and universally used.
If you value your Data do your self a favor and avoid the use of MT. Rainier and/or all other Packet Writing programs.
