Hi Lorin,

There is a problem somewhere in your methods. Follow the following steps:

1. Update to the latest version of PolyBoard (8.01k)

2. You could either restore previous parameters or find the problem files.

The problem will be in the materials folder, if you have a backup of your parameters delete the method files, open PolyBoard and restore your parameters.

If you do not have a back up of your parameters rename the folder Methods > Methods_old and create an additional empty Methods folder. Drag and drop one by one the files from the old to the new method folder and restart PB at each file until you find which file are broken.

Let me know how this goes.

Regards,

Isaac
