That's not very informative 😕

Anyway, please check this post: http://forums.ni.com/ni/board/message?board.id=170&message.id=224900&requireLogin=False. Is your issue the same? If so, you could try the workaround that one of the members has suggested.

Thanks for the link!  There's no workaround there but at least the problem is clarified and documented.

And the fact that this defect has been around since (at least) Jan 2007 is documented there as well.
