[Q] Kindle Fire; used Kindle Fire Utility v0.9.9, Browser & Terminal don't have root. topic

I've got a kindle fire that I rooted and installed android using the Kindle Fire Utility v0.9.9 (http://forum.xda-developers.com/show....php?t=1399889), and SuperSU is supposedly running correctly, but when I run root browser (by JRummy Apps Inc.), it cannot look into the /data/ folder, and trying to "su" on a terminal emulator gives an error. Any suggestions as to what might have gone wrong and/or how to fix it?

Thank you
