HELP – Updated Themify Erased Previous Headers/Footers

Hi – I have updated the Themify plugin and it erased some of the settings for my headers, footers, and fonts. I am not a software engineer or developer and had some help getting this created initially. I need this site fixed and back up and running again ASAP! I have saved a backup as of last night but am not sure if it will be enough. Anyone with experience/similar issues with this that can advise or help?? Dying for some support from an expert in this area! Thank you.
