Need clarification re: paid vs free and upgrade issues

So I paid $49 for this in 2015. But we’ve never paid anything since. In trying to post a ticket I see the price is now 5x that. So I thought maybe my problem was that I hadn’t been updating. After reading the pinned post I discovered that you’d done a major update in the last 24 hours. I was seeing the directory when logged in but no one outside could see it. I creatively just restored a day-old backup and I’m OK again, for now. But I don’t like running out of date plugins. I’m wondering if there’s a conflict with Divi and the new ajax stuff perhaps. UM is working with the restore. It’s Version 2.1.1 of UM and I have php 7.1 and WP v5.3.

So I need to know if I’m using this as a free version and should be getting help here, or is it a paid version? I posted a ticket before I figured out I could do a restore to get back to functional.

Thanks.
