Griddify - Not Generating Grids CS6

We just downloaded and installed Griddify (unzipped and copied to the appropriate folder per instructions), and when attempting to create grid lines nothing happens.

The Griddify panel shows up, we can enter numbers but no grids are being created.

This answer is way overdue (sorry :) ), but you can check these two things:

1. You measurement units must be set correctly.
2. "Show Guides" must be on.
