Rhinocam2 and Mach3 Problem

I have been happily using Rhinocam V1 and liking it. Ver 2 came out
and I just tried to use it and ended up with problems.

I was making a simple 2.5D part each time I tried to run the program
posted from Rhinocam2 Mach3 either gives me an abnormal warning light
with the cause being displayed as " Exact Stop vs CV Mode" or locks
up. I managed to get the one off part made but didn't like running
with a warning light on.

The warning light comes on when it reaches this line in the program

G81 X0.5000 Y0.2810 Z-0.6 R0.1

I'm pretty rank with both Rhinocam2 and Mach3. Until this they have
been pretty cookbook but....

Anyone have any ideas about this problem???
