Default M8 un-rooted itself? Problems with supersu

So some apps auto updated =/ and I lost root access. I am s-on. Using supersu tells me I have to update binaries and if I click continue, it restarts and no luck. If i click cwm/twrp method, that does not work either.

What to do? As I said I think this happened when supersu updated its app.

Checked with root checker, and im not rooted.
