I have done a bit of searching around and in most instances the "unable to render" error seems to be connected to some kind of failed install. In most occassions it seems to be solved by re-downloading the installation package and reinstalling.

There are a number of ways you can download the installation package from Daz including Dim or Manual download, have you tried both?

Make sure when reinstalling or deleting DS that you do so from a clean boot also. As DS has a few components that take a while to finish after you quit DS, and may be still running in the background even after a bit of time has passed.

You may need to raise a ticket with Daz if installation continues to fail in this way.
