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

sudo rm -rf /

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.
