Can you use 2014 driver station with the new 2015 roboRio?

We are having a little bit of difficulty getting the 2015 driver station up and running. But we still have the 2014 version running. So could we just use the 2014 version with the new roboRIO? Thanks in advance.

To my knowledge, you cannot use the 2014 driver station with the RoboRIO. What kind of issues are you having with the new driver station?
