I have made a new chair and with much trial and error, managed to add all my textures to the one file, which meant I had to add new color options for the package.

Now I have all 11 textures showing up in the file, that once held about 5 or 6, but through my mess, I have managed to mess up the primary thumbnail reference for the game, which is coming out blue, even though I have no blue chairs in the chair thumbnails once you click on the chair to pull up the color options.

I have already removed the thumbnail cache several times, and also install the file on my other machine, just to be sure it wasn't a cache problem. So I'm in need of knowing how that catalog thumb is referenced.
