It could be any one of issues. Best bet is to upload a capx so we can test it. You may get quicker and better help this way.
Here is a link to my capx.

First try making Layout 88s game preview loader be green most of the time and not red. Then you should go to either Layout 63, Layout 56, Layout 30, Layout 7, Layout 23, Layout or Layout 53 and make the game preview loader be green most of the time and not red. You should be able to make the game preview loader finish loading and preview the game and after that make the game preview loader be green most of the time and not red. You only need to make the the game prewiew loader be green most of the time for one of the layouts. If it works for one of those Layouts it should work for the rest too.
