The black background usually means that CC3+ cannot find the map file it is trying to load, so it simply uses the defaults (which is a black background). That in itself is nothing to worry about, as the background is controlled on a map by map basis. Everything will be fine when you load or start a new map.

Of course, the example map should have been loaded, so that seems to indicate you didn't get that file installed. Which may or may not indicate that the rest of the addon wasn't installed properly either. Best way to see that is to try to open the symbol catalog manually and see if it exists, and no red crosses in it...

Now, I see it is trying to show the no-SS6 version of the example, since I guess you don't have SS6, and I am guessing someone forgot to include that file in the installer (or gave it the wrong name), and the rest is fine..

And every citizen in every city prays it won't decide to come out and play with them.....
