Hello Ron,
If you have updated the theme to the latest version and need a backup of the older version (3.7.2), please check with your hosting provider to see if they have a backup available.
Also, if you are using a child theme, updating the parent theme will not remove your custom code.
If you need a fresh copy of different theme versions, you can download them from your Catch Themes account page: https://catchthemes.com/my-account/
However, please take a backup of the theme while updating to the latest version every time.
Please let me know if this helps or if you need further assistance.
Thank you!
Regards,
Sujeet
