Since subscribing I've tried to run the Livery designer on multiple occasions and not once has it worked. Even did manual install on the Unity Player. Have tried it in Internet Explorer 8, Firefox 13.0.1 and Opera 12.00. IE and Firefox both start to load and then give the error "Error launching Unity Player. Failed to load Unity dll."; Opera just leaves a blank white space.
