Janeet,

  Once you have made the modification to the proforma, save it, then 
right click on the component in your simulation and select "replace" 
from the context menu. Browse to the location of the modified proforma 
and click "ok"

  As to your other question, I am afraid that we are no longer 
supporting v16.

kind regards,

  David
