MediaMind MXP, Converted to ZXP, breaks and corrupts Extention Manager

I user the CS6 extension manager to convert the Media Mind Workshop MXP to ZXP.

Then I used the CC Extension manager to install it.  As per the instructions in Adobe's FAQ.

It freezes the Extension manager, and it never can be opened again.  Unless you uninstall and re-install.  (Restarting does nothing).
It half way installs the Workshop, but you cannot do anything with it, it just throws a JS error in the output

I have a delivery, how do I fix this. (Yes I msged MM, they said it is Adobe's Problem).  I hope you guys can provide better customer support then them.
