You will need the disc supplied in last year's KOP to get libraries and whatnot. Ask some local teams if they have a copy or an image of the disc you can borrow. Or, you can contact FIRST and ask for a replacement disc, or wait until next kickoff (only 74 days 16 hours 41 minutes and 36 seconds, not that I'm counting or anything
). Once you do that, install the updates found
here, make sure your cRIO is properly configured to use Java (that's set via the imaging tool), and have at it!
EDIT: that's probably not the most efficient way to do it, but it would work. See above post for the better way
