To purchase a reseller license you first need to OWN a level, any level inside Leaderboard Affiliate.
Once you have purchased the level, you will see a popup box appear at the top of your screen that will prompt you to purchase a license.
If you purchased a level and still dont see the box, you may already have a reseller license.
The way to confirm if you have a license or not is at the top of your screen you will see a new menu item appear for "COMMISSIONS / REFERRALS" if you see this at the top of your screen you already have a license active.
If you're still having trouble, submit a support ticket and we'll get back to you with a solution after we examine your account, please allow 3-5 business days for a reply.
