Fatal Error with Animation and Rigging Tools

I thought I had gotten lucky, but I guess not. Upon importing a custom character mesh and trying to place a skeleton with A.R.T., has suffered from fatal errors twice in a row this morning. This occurs every time I attempt to place a skeleton for my model. Is there a way around this?

The steps I followed were:

  1. Import character FBX
  2. Run “Character Rig Creator”
  3. Rotate character to be aligned with the Z axis
  4. Freeze transformations
  5. Accept default settings and place skeleton

This is when the crash occurred. I have the log files if they would be helpful.
