Nil Pointer Error

Just today I started getting a “nil pointer error” when trying to open .car files:

File: /Users/build/DAZDevel/Build/Carrara85/lnstallerScripts/Common/../../Src/Kwak/PublicAPl/RenderSettings.cpp
Line: 1257
A nil pointer error occurred while executing 0pen....

Target Helper files in the GenesisHelper folders will open. Files I create today, then close, will open. A few of my own created .car files will open, most won’t. Time stamp doesn’t matter, older and newer files won’t open. Fusion drive, external drives – location doesn’t seem to matter. I deleted preferences, uninstalled and reinstalled Carrara, to no avail. Interactive Renderer set to Software or Open GL makes no difference.

The only change I made recently was to clean out my fonts folders. But this didn’t screw up the menus, which is what usually happens when you aggravate Carrara fontwise.

Carrara 8.5.1 Pro Build 19
iMac (27-inch, Late 2013)
Yosemite 10.10.2
3.5 GHz Intel Core i7 processor
32 GB 1600 MHz DDR3 memory
NVIDIA GeForce GTX 780M 4096 MB graphics

Thanks in advance for any suggestions.
