Campaign requiring help!

Whenever I add a map, it always go in blue letters. When I enter the game, and into the campaign, it's empty.

How do you activate the maps?

Once you've added a map to your campaign through the campaign editor, click on the 'Loading Screen' tab at the top and right-click in the big white box. You should get an option called 'Add Button'. Click this and Fill out the two boxes titled 'Chapter' and 'Title'. Next click on the 'File Loaded' drop down menu and select the map you recently added to your campaign. Now your map will have black letters and will load properly.

But now, when I click the button for campaign screen, the screen goes black, and then comes back to the campaign screen.

Basically, my map isn't loading!

Come on! I need help!

The map isn't loading when I click it in the campaign screen!

I took my time to make a step-by-step with pictures tutorial. -->
