Purchased "Chief Architect Professional Design & Drafting Software" Version 10, in 2005. Unfortunately, my office was vandalized in 2013 and even though we were able to located most of the contents of the box, installation disk 3 was never located. Fast forward to today, computer crashed and we need to reinstall the program and even though we have the hardware lock key, of course the program does not work without the final disk being installed. Is there anywhere I can get/borrow the 3rd installation disk - I have searched the internet with no luck. Thank you.
