I do not know how to fix this, everything was working fine but now I can't post anymore. It always say's nonce is invalid. 

*AND PLEASE DO NOT JUST LINK OTHER NONCE ARTICLES, I HAVE ALREADY READ THEM ALL, NONE OF THEM APPLY TO THIS. THANKS! 🙂

If I uninstall and re-install won't I lose my comment history? I have not published my site yet with an actual domain tied to it, however it was working fine. I am seeing a lot of people complaining about the updates crashing their commenting system and was wondering if I should move on now and find another program? 

I really liked the idea of managing my own commenting system but I need long term security here. What happens if I get tons of comment history and then it stops working? Also I paid for all the upgrades a year ago but they might have expired.. not sure. Can't find any email or login account to show me if I need to pay again or if it was a one time upgrade..
