Hey there! Thank you so much for taking the time to give me such a detailed response. It always helps to hear other's thoughts and tips. As far as the quote from above goes I happen to know what your problem is... all the color schemes do work *BUT* when you export them to CC at first they will look blank because what you are actually looking at is a massively zoomed in corner of your map. You need to go to the upper right hand side of the screen and hit the "zoom to fit" button (it looks like a magnifying glass with a full rectangle drawn around it). Then you will be able to see the entire map. It took me a while and plenty of frustration to figure that one out.
You are correct that when first opened in CC, a world exported from FT will show a highly zoomed corner of the map. However, for me, some of these maps still seem to be totally blank (even after using "zoom to fit"). Further experimentation has shown, though, that the problem I mentioned seems to limited to export definitions that produce detailed altitude information. For example, even with a color scheme other than Default, the export definitions "Altitude Low Detail", "Fast Export", and "Overview" look like they work fine, whereas "Altitude High Detail", "Basic 1000 Contours", and "Full Export" manifest the problem.
And I tried just now to upload an example file for you, but EnWorld rejected it because it was too large. So I went back and tried exporting just a small part of the world. That did produce a smaller file, but much to my surprise it could be imported into CC just fine! So the problem really seems to be sensitive to a number of conditions. However, by generating a simpler world, I have managed to create file small enough to be uploaded that still exhibits the problem.

If you find a way to open this in CC so that the world is visible, please let me know.
Finally, I was incorrect about Raise/Lower Prescale Offset not being on the toolbar. They are right there, readily available. Sorry about that. I will edit my previous post.
