Activation issue - Hard Disk Manager 15 Suite

I can't figure out how to activate this software. When I log into my account at the Paragon Customer Portal, the My Products tab shows that I have a license for Hard Disk Manager 15 Suite that has not been activated. I have it installed on my PC but can't figure out how to go about activating it using my license key. Has anyone else had this problem or know how to solve it?

no activation necessary for HDM SP5. This infrastructure is only for HDM/BR 16, NTFS for Mac and several new products that need to be activated.
