I found a bug in the CK. When attempting an upload to Steamworks, if you try to add a picture BEFORE you have selected a catagory, the CK crashes out.

As a workaround, be sure you have selected the catagory first, then attach a jpg.

I've entered a bug. Thanks for letting us know.

Your welcome! You guys did a wonderful job BTW. Been doing mods since Morrowind and every year you guys just do us a solid. Thanks for making a great product and wonderful game.
