The cRIO is the long, heavy rectangular box that the 'cards' slot into. Has a lower section that has some dip switches, a serial port and two ethernet ports.
I would suggest going back to the beginning and making sure you didn't miss anything. Work through

Start a new workspace to do this, rather than try persevere with what you have. When you have got everything working successfully, and if time permits, then go back to your current workspace and try to figure out what was different.
