Accidentally changed multisite URL

Hey Guys-
I am pretty much a newbie at this, but with the help of my friend I recently installed a multisite to host a personal site at http://www.robnyland.com. I am hosting through bluehost.

After the multisite install, I created another site at http://www.robnyland.com/video — for my video work. I’ve been spending the last few days trying to do some domain mapping, and last night I accidentally changed the site URL for /video in my network admin. I quickly fixed it, but now http://www.robnyland.com/video just redirects back to my main site rather than going to the separate theme install.

I’ve looked through php admin and nothing seems to fix it.

Any thoughts?
