Good evening everybody,
I have installed Houdini 16 and used it a few times yesterday. Now I get an error message (attached to post) every time I open it. So far I have restarted my computer, updated video card drivers, and reinstalled Houdini. My video cards are 2 GTX 670s

I fixed it. Instead of updating the video card, I fixed it by uninstalling and reinstalling my video card drivers.
