Ultimate Banding Login Image Not Displaying

Good day.

I've done some searching through the support documentation but can't seem to find an answer to this issue.

I'm running WP 4.1.1 and the latest Ultimate branding plugin in a multisite/multinetwork installation. When I try to replace the WP logo from the login screen with our image logo (I've tried both jpeg and png type files and the image is 71X70 in size) it doesn't work correctly. I browse and select the file from my media gallery and save changes. When I do all I see is the small graphics box (with an x) that would usually indicate the graphics file isn't available. I've gone to the directory where it is uploaded (wp-content/uploads/images/16/2015/04/xxxx.jpeg and the file is there and has read permissions.

Any thoughts on why it won't come in?
