I'm having a similar issue here, only, mine fails to even start rendering.
iMac late 2015 Retina - Running El Capitan 10.11.6
4ghz intel core i7
32GB RAM 1867 MHz DDR3
AMD Radeaon R9 M395X 4096 mb

How, exactly are you trying to do the render? There are now a couple of different ways things could be getting done. At what point in the process do these error messages happen? If you are able to get to a render settings box, what are your render settings?

We haven't seen you return to this thread. Is everything OK? Please let us know if you solved this issue yet or if you still need assistance.
