Hello, Yasonok,
You can activate XStore now.
Please note that according to the ThemeForest license policy, you can use 1 license for 1 project only (dev site, production site, localhost but the same project), read more – https://themeforest.net/licenses/terms/regular If you want to use our theme for a few different projects you need to buy a few licenses.
Kind Regards,
8theme team
