Sure! While I appreciate your quickness, you should only mark as received a game that you have actually received and activated. If I were to send you a fake key or no key at all, you will show up as breaking a rule and might be punished for it!

But when I checked your user for unactivated wins, you showed up as not activating this one! I knew why that was so there's no problem there, but you'll have trouble getting through SGtools barriers and might get blacklisted by some people if they see that in your profile on the timeframe between marking as received and actually receiving and activating the key
