You edited the image sizes wrong in your functions file. You only put 150 in the code, when it should be a width and height (which would be 2 sizes).
example – add_image_size( ‘home-bottom’, 290, 150, TRUE );
I edited your functions file back to the original code (since you said you wanted it to look like the demo), then I selected the 290 by 150 with the Genesis Featured Page widget and regenerated your thumbnails for the 1st widget (you can do the other 2)….Now its working.
