I sent an email a copy of one of the test images. --- Email:
I changed the font to a standard font, Arial Bold MT, color white; checked Add Stroke, 1 px, color black. Everything else remained the same [as the screen shots above.]. Attached is one of three images in the test folder; all three have the same attributes as this one. NOTE: Before I checked Add Stroke, but after I changed font, I ran a test and the plugin worked fine.
Thanks for your help.
