jeez, stuff just doesn't seem to work anymore.  
Lotsa bugs in the Zt3a and Rapture Pro, but thought I'd take the plunge and update them (waiting since I bought them back in May)
Command Center doesn't work for me after a new install, shuts down right away
 
That's not good customer service.  :(

If you are running Win10, there is a known issue with the Command Center which has been addressed here http://forum.cakewalk.com/FindPost/3343922

Thanks from Austin-   that did it
