Is there a fix for an NXT reporting "File error!" when running an EV3 program? 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.

It downloads without complaint.  Run it and the NXT complains with "File error!".

Is this a known problem?
Is there a fix?

The NXT has firmware 1.05 loaded.
I needed to update the firmware. 1.05 was too old. 1.31 works.

I did need to run the old NXT-G software to download the newer firmware.  I did not try to download the firmware using EV3.
