Please help me out to resolve this activation problem

I was able to find only a free license for ESET Mobile Security registered to your forum's registration email address. If you actually purchased a license for ESSP, make sure that you enter a license key for that product.

If you didn't purchase any license yet, you can activate a fully functional 30-day trial license in the activation window.
