I have been having so many problems with the latest version of Bryce 6.1 that I finally called DAZ to see if I could get some real help.
 
It's at the point where I cannot do a thing to create. From not being able to save, import, export, HDRI and even render.
 
Here's what they told me. They are aware of all the bugs in the latest version of the software. Everything I explained as a problem has been reported to them from numerous users. Their development team is working on a fix and will post as soon as an up date is made available.

I was told if I had any older copy of Bryce they should still work without all of the problems. So dust off the old copies and reinstall for now.
