Noob SfML owner and I can't seem to get light out of intimidator 250

hi, I i recently purchased  the SfML and I've loaded profiles for all my fixtures.

And , so far I can get all of them to work, more or less as expected.

except for my chauvet intimidator 250s. I can make them move and I can hear the gobo Wheel spin. 

But no light comes on. I know that (as on my intimidator 150s,) that light requires both intensity and shutter being open.

but when I move the faders that are mapped to those channels (from the profile), nothing happens.

im using the advanced profile if that matters.  Although i think I tried the basic one as well and same outcome.

id love any thoughts or suggestions of stuff to try.

thanks!
