Answers.Body: <p>First off Ev3 and Nxt are different machines. However, it's most likely the firmware. I've just downloaded my firmware for Ev3 and I also tried out a program I made. It downloaded perfectly but when I tried to start it, it said "FILE NAME ERROR", which I believe is similar to your problem. I either recommend re-downloading the firmware or turning the Ev3 or Nxt off then trying it again.</p>

  I downloaded the new EV3 software from Lego and installed it on Windows 7. The EV3 software runs. I plugged in an NXT using a USB cable. EV3 can edit the memory on the NXT and remove programs/sounds/text files.
  
  I created a program that uses the large motor to spin the B motor 1 rotation at 75% power. The end program block finishes the very small program.

  Is this a known problem?
  Is there a fix?
  
  The NXT has firmware 1.05 loaded.
