Reference files for all objects have suddenly dissapeared?

    I have no idea what's happened. I did nothing (that I know off) that could possibly have had an effect on anything in my Max folder, but now I can't open to reference files for any object. Help files are intact however. I'm also not able to view the online reference files, which doesn't really make sense to me either.
