Default [Q] re-rooting of S3 I9300

I am using galaxy s3 I9300 since last 4 months. Last week i rooted this phone and very next day i upgraded it's android to 4.3. After that my supersu says that "there is no su binary installed and supersu cannot install it. this is a problem. if you just upgraded to android 4.3, your need to manually re-root - consult the relevant forums for your device." Then again i rooted my phone but now this time my supersu was not showing in all apps, i again rooted 2-3 times, but still my supersu was missing. Then i downloaded supersu form play store and installed.

Now my custom binary is 4 and SuperSu is still showing the same error (there is no su binary installed and supersu cannot install it. this is a problem. if you just upgraded to android 4.3, your need to manually re-root - consult the relevant forums for your device.)

I used Triangle Away.apk to reset the binary counts but this is also asking for root access and my supersu is not working...

Please help me in this..
