Might and Magic GOG Galaxy Help

I have been playing the Might and Magic games for a while. I downloaded Might and Magic 2 off of GOG Galaxy and have been playing it for over a year. Unfortunately, I made an error in the game. I don’t know how to fix it throughout searching on the internet. If you either know the in-game way to fix it (if there is one) or a way to recover a save from before, I would greatly appreciate your help. I do not want to lose so much progress in the game. Please be aware that I do not understand coding or anything. If you have a solution, explain it to me like I’m five. I apologize if there is not enough information in this post to get help, let me know if I need to add details. I also apologize if this is not the correct place to post this. Thank you!

You’re going to need to be a lot more specific, I assume reverting to an older save is not an option?
