access denied - please check site registration

I have this installed on a network installation and I registered my domain. When I go to view any videos on a site, there is a big graphic that says Access Denied - Please check site registration. I went back to check site registration on my network dashboard and was prompted to provide my wpmudev login and password, which I did, then I was prompted to enter my domain again, which I did. Still not working on any of my sites! Please help!
