If you bought our themes, you should add your purchase code for installing themes without trial mode.
From the Boostheme Toolkit app, click Manage licenses on the top menu.
Then add your purchase code in the input field.
Then click the Activate button. After that, your purchase will appear in the Your activated licenses table below. That means you activated the license successfully. And you can click the Install theme button to install the Beloria theme on your Shopify store.
