Have you tried downloading a simple While loop with just the Arcade motor command? Like the programming manual shows for Tank control (pg 8-46), only put in the Arcade - 2 motor control (assuming you are using 2 drive motors).

On my robot, the motors are on ports 3 (left) and 2 (right), so I used the settings Arcade2 (0,2,1,3,2,0,0) to map the right hand joystick left-right (ch1) to rotate and fwd-back (ch2) to forward/reverse.

Watch out that the Vex Help file example for Arcade - 2 motor has the transmitter channels swapped (fwd/rev to ch1, rotate to ch2). Makes for an interesting driving experience!
