Another leaky shower drain
Hi! A few weeks after moving into our (12 year old) house, we noticed moisture coming through the ceiling. The upstairs shower is right above the wet spot. We called our warranty company, and they sent out a technician who said that it was the shower drain, which has a crack in it (but of course, he said that it wasn't covered by the warranty due to some fine print or other.)
I found the plumb-rite website and ordered their wing-tite drain, in the hopes that we could fix this ourselves. Sadly, I've already run into a problem: I can't figure out how to remove my current drain, and to my inexperienced eye, it doesn't look like either of the two drain varieties pictured in the wing-tite instructions for old drain removal. I can't see anything that looks like the gaskets pictured in the instructions, or anything that I could remove, other than just the whole drain itself.
I am hoping that someone here might be able to take a look and tell me what I need to do to remove this:

Thanks so much for taking a look--I looked through some of the past shower drain posts to try to avoid wasting anyone's time, but I didn't see anything that would answer my question.
