The error you're getting doesn't seem like anything to do with the issue, as I got it on my map once and clicked OK and haven't had it since.

Does it happen on all maps or are you not able to create any at all?

yes happens on all the maps, in radiant F8 is all black and white

information for other people that has this error:

VRAM may be causing it.  System requirement is 4GB or more.
and my GTX 780 has 3GB VRAM.

The following are minimum system requirements to run the Mod Tools for Call of Duty: Black Ops III. We expected the requirements to be higher for the tools and were pleasantly surprised to see during the Alpha that some machines with lower specs could run parts of the suite. It is possible to do certain work on lower specification machines but in order to take advantage of the whole suite of tools we recommend using a computer of this caliber or higher.

CPU: Intel Core i7 2600 @ 3.4GHz / AMD FX-8350 @ 4.0GHz or higher (SSE4.1 support required)
OS: Windows 7, Windows 10 (64-bit OS is required)
GPU: GTX 770 / AMD HD 7970 or higher (SLI and Crossfire are not supported)
VRAM: 4GB or more
RAM: 16GB DDR3 or more
