I just recently purchased a new action set from Greater Than Gatsby actions. Every action has worked for me except one in particular called Rich Matte Finish. Everytime I click to play that action I get an Error Box that says "Could not complete the command because that content type is not supported for this color mode." What does that mean and how do I get rid of it?? I have contacted the owner of the action set and they tried it on CS2 (which is what I have) and it works fine.
I use Photoshop CS2 for this action set and my PC is Windows XP
Above is a screenshot of the error box.
