Admin Access Denied After DB Change

I had some issues with my host's automated upgrade tool to move my existing WP install to a new server. For some reason the tool in this case rather than moving the existing database to the new server created a new datacase with a basic WP install.

Host support jumped in and manually migrated the content from the old db to the new one. This brought the site's front end back (yay!). However now when I try to access the admin dashboard I get a "do not have sufficient permissions to access this page" message (boo!).

I have done some research into this issue and figure it may have to do with the database name change. Things look okay in wp-config.php.

I was hoping support here may have some proven resources that they can share in case I am forced to resolve the issue myself.
