Fresh install and no admin access

UPDATE/ANSWER: I just had to update the Nameserver (DNS) records to point to my host server, duh, silly me!
I had "successfully" installed the UNA software (via my TMD Hosting cPanel) with my own GoDaddy domain.
The last part of setup, where I go to my domain+ add " /studio " brings back a 404 error. The domain still works fine though. I have no access to admin login anywhere...
I know it must be a user error (me) lol because this same issue occurs when trying to do the same with other cPanel script downloads.
I can not seem to find troubleshoot info on the steps beyond install when getting to login as admin.
