I bought my first version of Carrara years ago. I'm still waiting for documentation. I waited a year or so for DAZ to release a Mac version that worked with the current version of OS X (was it Lion?!). I wouldn't buy Carrara content if I couldn't use Carrara! DAZ never compensated us for lost time. They just went ahead and charged for updates.

Yup.  I complained about the documentation issue, all I got was soundly flamed in the Forum by the DAZ defender posse.  I filed a couple of support tickets, but never a peep from DAZ support, management, etc.
