Note: There is no risk of losing your settings and pages when you update the theme. However, any modifications you have made to the core theme files will be lost, so you should back up those files before you update the theme.
Note: You will need the Token key you had generated when you had originally installed the theme. You will find this under the Settings > API Keys section of your profile on Themeforest.
Tip: Make sure your unzipping software does not create any extra directory with the same name nested within the manufacturer\ folder.
Note: The FTP program will give a warning that the manufacturer\ folder already exists. Choose Replace All.
