Thank you, bepeg4d. You are a genius!

I just installed the 3.2.17 CUDA toolkit, per your suggestion, and everything works fine. It would never have occurred to me to install the toolkit as I was focused just on the drivers.

A million thanks for your help!

Thank you so much for the suggestion, bepeg4d.
Unfortunately, reinstalling 10.6.6 combo did not solve the problem for me.

Grateful for the ideas though!
Best,
Ed

Program opens fine -- seems to be communicating with OctaneLive account just fine. All other windows and nodes behave fine. Voxelizing OK. But...when I click the primary object node (the "click me" node) the program crashes.

(This does not occur with the 2.3 V5)

Any thoughts? Many thanks in ...
