Iray Preview broken?

I just updated to the newest version of DAZ Studio (14.20.0.2) and now the Iray Drawstyle of the Preview port never displays.
It just says "Preparing Scene..." in the status bar but never shows an Iray preview.
Is it broken?
Comments
In fact, I can't even do an actual render now.
Did this release break something in the render engine, or do I need to change my settings?
Please help. This has happened at a most inconvenient time!
Is there a way to back out of this update?
It was working fine last night. Then I updated this morning and it's not rendering anything. The render window finishes in seconds with no image, just transparency.
Iray updates often require driver updates too. Have you tried this?
(Also, check the log files for specifics).
Tried to just render a primitive sphere, nothing! Just a blank render window.

Your nvidia card driver is outdated - needs an update :)
That worked. I updated the driver.
