Yutaka,
Those error msgs are from a communication error between the PC and the
Ariel DSP.  Brad & I are sure that it is a strange S/W problem that shows
up on some projects and not others.  You should definitely re-load the
application (469D) software when this occurs, because you have no idea
what data area got corrupted.  Hugh Sparks is looking into the system
s/w to try to find the exact problem.
