Try to (1) deactivate the theme in XStore > Dashboard and activate it again using your purchase code. (2) After that you need to go to WP Dashboard > Updates > press “check updates” link to force check and clear cached links and only after that try to (3) update theme and XStore core plugin. OR do the update manually – https://xstore.helpscoutdocs.com/article/63-theme-update https://xstore.helpscoutdocs.com/article/37-plugins-update
