Proposed not working?

Hey guys,

I've used Kubla successfully a few times in the past, but it's been a bit since the last time. It seems like the program isn't calculating my platform element. I've gone through all the videos and read the forums but I can't find anything to help.

Other things not working correctly:

• No cut/fill calculations are displayed on the proposed tab's top left.
  
• The 3D view is not working.
  

I've attached a screenshot of my program since these forums require a URL to link a pic.

Thank you!
-Will
