It sounds like you have to reinstall. Before you do that, try a mass compile on the directory where those VIs are installed (the entire NI directory if you have to.) There was probably a problem during installation that caused this problem. I have seen similar, though not with these VIs, and a reinstall fixed the problem.
Also, try contacting NI support on this one. It doesn't sound like something that should be happening. If you don't get a quick response from this forum, you may be able to get a faster answer going through support.
