ASI1600GT filter wheel control

DaveCC

My ASI1600GT filter wheel cannot be controlled by ASI Studio ver 1.4.1. The filter selection is grayed out. I have not tried with any other versions of ASI Studio. I have searched the 1600 manual and the filter-wheels manual.
Can you help? Thank you.

Can you please try other version then we can figure it out it is a bug of new 1.4 or something else?
