Hi,
Yes you have a license but your license wasn't attached to your website.
I have manually attach your license to your website. It should work now.
You can see your licenses in the "My Account > Your subscriptions" :
www.hikashop.com/en/account/your-subscriptions.html
Sorry for the inconvenient.
Best regards,

By the way, do not send me private message, use the "contact us" form instead.
