Does WSN Gateway show up if you select New Target or Device?
My guess is not. That would indicate that you don't have the WSN drivers installed properly. Did you install them after LabVIEW? Is the version compatible with your version of LabVIEW?
EDIT: In the future please post this, but I was able to look at your screenshots and figure out you have the 1.2 WSN driver and LabVIEW 2011. These are not compatible. You will need the 1.3 WSN driver.
