VESC not responding to Controller

Using the VESC tool, I updated my 4.12 Flier VESC from 2.54 Firmware to 3.34 Firmware. The update was successful (according to the VESC tool), but now the VESC will not respond to input from the controller. The VESC was communicating fine with the receiver until after the firmware update.  I have tried a few things to troubleshoot this, but no success.

Transmitter/receiver –

1. Redid the binding process – still not communicating
2. Tried all channels – Still not communicating
3. Tried using another VESC to insure the Transmitter/Receiver was working correctly – Worked fine on 4.1 hardware/2.18 firmware
4. All lights on Transmitter/receiver indicate that the connection between the two are active/correct (ie: steady light on both)
5. Tried a different Transmitter/receiver – still no communication (but this trans/rec works fine on second VESC)

2. VESC –
   
   1.  Reapplied Firmware update – still not communication with controller
   2. VESC tool communicates with VESC correctly – can change settings, they are saved and applied
   3. Rebooting VESC after each change – still no communication with Receiver
   4. When using the VESC tool, I can control the motor and it functions correctly (ie: The motor accelerates/brakes/etc. using the arrow keys on the keyboard).

The problem seems to be with the VESC recognizing the receiver.

Any ideas on what I can do to solve this?
