Reminds me of something I heard once... Software guys tend to always blame problems on the software, and insist it can be fixed in software, and almost never even consider the fact that it could be a hardware thing. I know I'm usually guilty of that. Same idea applies here, I think.

Unfortunately, I can't help you any further. :-/ It would take someone more knowledgable of 5.004 to tell you why you're getting the warning under it.
