It sounds like you might be having trouble because you do not have the Full Package of LabVIEW. The Full Package comes with several advanced analysis VI's that the base package does not include. This would explain why so many of the subVI's are missing. I'm afraid there is no place you can just download the VI's, you have to get the full package. If you are curious, you can look in the NI catalog on page 74 to see what things are not included with the Base package of LabVIEW. If you do have the Full package, you might want to be more specific about which VI's you are having trouble with.
