The problem was actually with the preview FCW files for the vegetation drawing tools. Some of them had effects enabled, which can cause problems with the preview in the catalog window. Unzipping the attached FCW files into System/Drawtools/Annual Ferraris Style/ should fix the problem.

This was a temporary problem a couple days ago, when Humble Bundle ran out of serial numbers (they are bad in lettings us know in adavance to get more). Since then we provided them with new serial numbers and were hoping these would last.

If this problem persists, please let us know which products are causing the error (the HB page should indicate) and we'll poke them with more serial numbers to add. As soon as they have added them, you should be able to retrieve your keys.

Open Symbols > Symbol Manager, EDIT one of the symbols showing a red X and use Info > List on the red x rectangle.

That should show you the location and image CC3+ is looking for in the map. Copy the missing images there, restart CC3+ and the symbols should show again.

If you can't resolve it, post the FCW file of your map here, so we can take a look.

I would recommend one thing, that I didn't do in the video: Set the starfield background fill (Starfield_06) to be scaled to 10 units. In the template it's not set to a fix scale, which means it looks good on screen, but not so good on the export.

SS1 and SS2 don't have their own buttons. They just add styles and assets to CC3+ and DD3 respectively and make use of those buttons. Just start a new map in one of the styles headed by SS1 or SS2, and you'll get access to those assets.
