Okay, we figured it out!
Here is what we did in case anyone else has this problem:
1) Followed these directions for installing labVIEW completely:

2) Following the instructions for the update suite completely:
https://wpilib.screenstepslive.com/s...-all-languages
3) Download all NI Updates (one at a time and restart after each)
4) We also used a different USB A -> B cable to connect to computer
The computer finally recognized the roboRIO, so we'll configure it today!
Thank you all very much for the help, we really appreciate it. Good luck!
