What "VEX" are you using? The PIC, or the Cortex? What have you tried doing? What lights are blinking on the micro controller?

First, follow these steps to redownload the Master CPU Firmware to the Cortex:
- Start with the Cortex turned OFF (but with a battery connected).
- Push and hold Config button in on the Cortex.
- Attach the USB cable between the PC and Cortex.
- Wait for the Robot, VEXnet and Game lights to blink green.
- Release Config button.
- Turn the Cortex ON.
- Then in ROBOTC, click "Robot", "Download Firmware", "Master CPU Firmware", "Standard File".
Once the Master CPU Firmware successfully downloads, download the ROBOTC Firmware to the Cortex.
