Hello,
Sorry for the some delay in answering.
1) To get XStore license you need to go ThemeForest and buy it.
2) After that submit refund request for the Legenda theme https://themeforest.net/refund_requests/new
3) Once you did that reply back here and provide me XStore purchase code in private content area. We’ll check it and confirm Legenda refund request.
Regards
