You may not to be able to connect for a few reasons.
- Assuming you are still using a cRIO on your 2014 robot, you will need to change the protocol on the Driver Station under settings to 09'-14' DS & FMS
- Your bridge may still be in competiton mode. If you have not re-congfigured it since your last competiton (including off season events) you need to switch the switch on the back of the bridge to "AP" and re-configure it using the bridge re-configuring tool.
