No need for any credit. This was just a fix I did for myself to look at some TRI files and then decided to share. I'm really glad that you are now back updating the scripts!
I updated this Plugin to work with Blender versions 2.80.0+ I tested it in 2.80.0 and 2.90.1 and it should work. No new functionality added, just API changes. I'm still a beginner in all things Blender, so let me know if you run into any problems. Edit: deleted files since PaulGreen updated the scripts again
