Just have to add this here for those looking for more answers as I was.
I read the fine print (or so I thought) and waited the full 45 days plus a week for the sign up bonus to appear before wondering what was up. The automated chat support informed me that since I have had premium in the past, (Years ago, returning player) that I was ineligible for the bonus. I must have missed this before and I'm sure others have as well.
So. if you are still waiting for your bonus and have ever had premium before then don't hold your breath.
