Forgotten MCreator PC username fix plz?? Pt I.

Somehow something happened while I was logging into my account on my Windows PC, for Some stupid reason I’ve been locked out of my account. I’m not kidding either I’ve been trying 5x now but I can’t seem to make my way out of the stupid “There has been more than 5 failed login attempts towards the account” Prompt, SOME MODERATOR NEEDS TO HELP ME SOLVE THIS AS I CAN’T EVEN USE MY USERNAME EITHER and if I can’t do something about this soon I will be forced to take down my WiFi because I can’t access mcreator. Without this prompt fixed first, “You are using an outdated version of MCreator” it keeps popping up like crazy and I don’t want to upgrade either because if I do that I will be forced to use the 1.14 version of Minecraft and if that so does happen I can’t use the older versions anymore because they won’t show up at all during the Mod making process, I might do a follow up to this forum topic sooner or later. But assuming I can’t take this prompt anymore (or any other prompts for that matter) I figured if I use my iPad instead than I may have a reason to fix this “glitch” as well. Thank you admins for your help and I might as well come back later if this “Account issue” is yet fixed or reset or not.
