[Shipper Pro] Trying to migrate my MS over to you and eventually everything Shipper doesnt work li

I'm trying to move over to you guys all of my sites but it will be a slow and arduous process. I want to start by moving my testing MS and then work on getting my domain mapping straightened around since I never have gotten that to work but I need to start by getting my site over to you.

I have granted support access to the site.

I try to do the preflight and it cannot get past the first step.

Thanks for the help.
