Not creating new licenses on new orders

Whoever using this plugin and seems it don't work, please make sure the "downloadable" option in product is checked. Also in the plugin setting, input the creation key (not using the activation key).

I use the latest WordPress, Woocommerce and Software License Manager, and every is work as it should.
