[VW crash when sending to Vision]

Is there a good tutorial on fixture modes somewhere? My searches haven't turned anything up.

 

Also, when i go to edit the fixture mode in the OIP, the drop down is set to 'None' with "Other...' underneath, but when I click that, nothing pops up.

 

all of the symbols I am using are Vwx symbols.

 

UPDATE: -- 

I created a document with only an extrude, and an S4 36º, and even when exporting esc I get a crash, and I can't seem to figure out the fixture modes...

Hey,

 

So I'm, having this exact problem, but on SP3, on a Mac. 

 

I checked my Plug-ins folder, and the "RuntimeCache" folder doesn't exist.

 

Thoughts?
