Fireworks is asking for a serial number and says "my trial has ended"

I have a full CC subsciption and yet Fireworks is asking for a serial number. I have tried all the typical things (logging out of CC, uninstalling Fireworks, etc). Doesn't work. I've read several other posts on here but most seem to be dealing with Windows and the steps given aren't available to me. I'm running it on a macbook. Absolutely no problems whatsoever with the program until today except it has been telling me my "trial" was ending. I ignored it, assuming it was a glitch I've been getting more and more of those from other adobe products. Just learning to live with them I guess. I don't have time to stop and fix things that are still working, but now that Fireworks has basically just quit on me I'm screwed.

My subscription to CC is renewing in a few days. Would probably have to cancel if this issue can't get sorted out.
