Hello,
1. Please set widgets in Appearance > Widgets from Inactive area to footer.
Also, next time you can update theme via FTP https://www.8theme.com/documentation/xstore/theme-installation/theme-update/ without deleting old theme version http://prntscr.com/l7ke7k
2. Do you have a backup of your translation files? Please upload them in /wp-content/languages/themes/ folder and continue translation.
Regards
