Party and Raid frames suddenly nonexistent?

[Kaleesh]

Actually, the Raid Profiles tab under Interface doesn't even exist anymore...

This persists, on every character I've tried, no matter what settings I tweak, even if I disable all addons, and there isn't a single unitframes addon that will get them to show. Not sure what to do, and I'm not really game for destroying my entire WTF folder. Someone told me doing so might fix it, but I'd like to know if there's just one particular file in my WTF folder I can delete instead of the whole shebang.
