Bah, I didn't save it. I've deleted only the lights without deleting the phantom geo and poof, renders, still throws out the errors but it renders in like 13 secs with the original render settings anyways @_@ Argh! I'll be poking around some more because I'm curious about what is going on here. I don't know if it's something in 2013 that isn't going over well in 2012 or what. Not being able to find a texture is understandable but that other stuff I don't know.

The first set of errors I get when rendering the rest when the file opens.

Try recreating the lights and giving it another shot.
