Particle illusion standalone or Continuum "Internal data stream error"

I have both the free FX partical illusion Standalone, and the Continuum Particle illision that came with vegas 18 pro suite. I have a windows 10 pc running 64bit. If I try to render “Anything” other than the .MOV file, with the Apple driver, I get “internal data stream error”. I read on the internet to install k-lite codec pack, so i did, and no dice. same problem. has anyone else ran into this? and if so, how did you fix it?
