No Max 2014 is not yet supported, should be done soon.

I have 2014 x64,and it has this bug everytime I create a mountain.
I also tried it in Max 9 and it works perfectly.
So it doesn't support 2014 yet.

I tried the trial, and with default settings I got bad result at the peak of the mountain. Check the image:

Heavenly Pictures,

It uses a random seed every time to create the mountain. So rarely it happens that the randomness is too much. Simply delete it and make a new one.

If this is happening everytime you create a new mountain, then you can try these:
1. Restart 3ds Max and run again
2. Try it on another version of 3ds Max (versions 9 to 2013 are supported)

Oormi Creations.

Nice but you should work more on Dunes.
