From what I can gather it sounds like you have done everything right (although it would be nice to see your code). If you have not already, you could try using the included example called Solenoid with Compressor Example. It's available in the Getting Started window when LabVIEW starts up. If you already have LabVIEW windows open, select View->Getting Started Window... from the menubar. If you don't see "Solenoid with Compressor Example" in the Getting Started window, then click the More... button for the Examples in the lower right corner.

Do you have a way of posting a schematic of your wiring hookup (even if it's a scan of the the drawing on a napkin)?
