Adventures with a Sense 3D scanner

I have a problem.
I got a used 3D Systems "Sense" 3D scanner as an Amazon warehouse deal.
(Same manufacturer as my CAD Software, so they integrate perfectly.)

The package did not include the activation code.
Some former user has already activated the software, so I can't activate it.
Amazon has no information about the former owner, so they can't contact him/her.
3D Systems does not answer the phone on their German hotline.
So I just sent them an email about the issue....maybe they can reset it or give me an activation code.

Update: Wow! After 17 minutes I git an email with an activation code asking for my user-name, so it can be associated with my account. That's damn fast customer service!

Notes:

• I'm using 3D Systems Geomagic Design as my CAD software. Since they don't have a MacOS version, it runs in a VM with Windows XP.
• The Sense software installs on XP but crashes on start. Only Windows 7, 8 and 8.1 are supported. :(
• The Sense scanner registers with Windows as a Carmine Primesense and works with Skanect just like a Kinect but has MUCH BETTER RESULTS then an XBox 360 Kinect V1 sensor. (My Kinect V2 for Windows is not supported yet.) Also more ergonomic to handle.
• The MacOS Sense software is not signed by a registred developer, so at first MacOS refuses to execute it unless you enter the system settings and add an exception for this program. 
• On MacOS the Sense software FREEZES MY MACBOOK during entry of the activation code. No mouse or keyboard anymore. Not so on my desktop iMac.
• The Sense software looses track every 2 seconds where Skanect works just fine, display a white page instead of the scan result and offers only ".ply" as an output format, no STL.
• Displays a static image on the iMac. The movement commands for touchpad and 3-button wheel-mouse don't work (with a 1-button mouse).
