SuperSU still needs SuperUser permission to run, but follow the below, and I will get your Root back.
This is an easy fix... Go into the first SuperUser app that you have the one with Android with the "eye patch", then slide the screen to the left,> look for the "su binary v1.xx:SUPERSU" below that tap the screen on "tap to check for updates" this is updating the binaries. If this goes through and you receive a message at the bottom of the screen says something like, "that was cool do it again." Then success and you have root.
If you receive an error and will not go through, download this app SuperUser Update Fixer , then run this app, So you are aware this app will not work, it will remove the bad installation of SuperUser, then go into the playstore or download this link for SuperUser, which go ahead and install it, open it slide the screen to the left and update the binaries, which this is the "tap to check for updates", approve whatever pop-ups and you should see the, "that was cool do it again" message (of course no need to do that as Root is back in order.) Then you can setup SuperSU, click the continue option. I also suggest installing a copy of Busybox it works nicely with SuperUser and SuperSU, here is the link for Busybox.
Hey there. Thanks for the instructions. I followed through with everything that you said, in order, but then received this message when trying to update the binaries. First error when trying the app on it's own. Then the same error after downloading the following two apps you listed to fix it....

I did how ever, get the Superuser to do "That was cool, do it again!" after repeatedly pressing it.
Just to clarify you don't actually need to be rooted to flash custom ROMs, on all devices. Basically you need to be able to replace the stock recovery image with a recovery image that allows the flashing of unsigned zips. My droid DNA, for example, I did not have to root to flash a custom ROM. I went straight to unlocking the bootloader, and then flashing a customer recovery image via fastboot. Then when I flashed a custom ROM it already had the SU binary installed.
So, what I use root for:
Use ROM Toolbox Pro to freeze carrier turdware.
Use ROM Toolbox Pro to overclock my processor.
Create root SSH sessions to manage my phone.
Install other various root based apps such as a call recorder app.
Use root to do cellular network diagnostics, that require you to change the way you use your radio.
Other random awesomeness.
