You need to install the 2011 LabVIEW Update. Bookmark this page:
http://www.usfirst.org/frc/kitofparts
Go to the link for "Getting Started with the 2011 FRC Control System." It has links to all the updates you need for LabVIEW.
While you're on the KOP site, make sure you get all of the updates downloaded for your driver stations as well. When you get to competition, if your cRIO, LabVIEW, and Driver Station all aren't on the latest rev, you won't pass inspection.
Good Luck,
