I need help with my domain mapping woes

I have followed seemingly every domain mapping guidance out there. I just cant seem to get it to work. I was on host gator, I dont recall this being much of a problem. I have Hover as my registrar and am using godaddy for hosting...Hover says its Godaddy and vice versa, but both also say its the WPMUDEV Domain Mapping Plugin (which I do not think so, because its seems to be more feature packed then the one from the Wordpress repo.

I have Googled, I have Youtubed, I have called, but I still get the attached error.

I just need help step by step, how to point my domains from hover to godaddy and have them resolve in the domain mapper...help
