I have been having a devil of a time trying to remove my shower drain cover.
I'm in a 2007 MADP, and I've attached a pic of the drain cover.
I have tried prying it out. Screwing it out (looks like a slotted screwdriver hole in the center).
I've gone around the outer edge with a utility knife to break loose any silicone/sealant. And as you can see the knife slipped and marred my shower floor badly.



But the stupid thing simply won't budge!
Am I missing something? Is there a special trick to it?
