Hello, and welcome to the forums!
There are a couple of things that stand out to me: first, the battery attached to the Cortex is low (3.3V) and may be causing corruption when you try to download the firmware/programs. Make sure the batteries have sufficient charge before downloading any firmware or programs and it will save you a lot of headaches.
Next, I see you have the VEXNet Joystick attached to the computer but it's not connected to the Cortex at all. We have a tutorial that can walk you through the process here
Could you post the code on here (using the [code][/code] tags) so we can take a look at it for you?
Edit: Also (I missed a big one here, thank you Jesse for reminding me) check to make sure your motors are plugged into the correct ports (2 wire in the 2 wire ports, 3 wire in a 3 wire), ROBOTC is configured for the motors correctly, and that the motors are not plugged in backwards (they are keyed to the microcontroller).

And this is crazy,
But here's my code now,
So fix it, maybe?
