When upgrading to a newer release of Site Store Pro you do NOT need to reinstall the entire application or database. You simply have to download the latest version and then replace the /estore_admin/ and /sitestorepro/ directories with the folders of the SAME NAME located in the ‘UPGRADE' folder in your new zip file. Replacing  ONLY the ‘estore_admin’ and ‘SiteStorePro’ folders prevents the possibility of overwriting design files that were changed after your original install date.
