That can't be it, because he's completely locked out of everything DLC related now. It's as if it's no longer recognizing that he bought it.

See if his PS+ is expired. I'm not sure off the top of my head, but it could be possible that it requires PS+ to be active to use.

That's really the only thing I can think of that would hinder content you've already bought.

You should also be able to uninstall the DLC and redownload it via PSN, that might be a possible fix.
