Maya goz shelf reinstall

Hi all, my goZ icon disappeared from my maya shelf, and if I manually re-add it does nothing.
Sooooo I deleted the shelf and reinstalled. No button, and no luck. But then I noticed that if i just delete the shelf, then restart maya, that the shelf still automatically reinstalls (with the popup saying that goz is ready to go), even though I havent reinstalled from zbrush.
Can anyone please tell me why/where it is reinstalling the shelf automatically without my instruction. I’ve tried looking in all the userSetup.mel’s and userPrefs.mels, but cant find any installation commands in those.
I figure if I can stop this, then perhaps I can get a new version reinstalled and working properly.

any help appreciated.

cheers
