I am sorry you're currently not able to collect your early access key for NBA 2K27 at the moment.
We are aware of an issue affecting many other digital Steam key retailers and we're all working with the suppliers for an urgent update.
There are also reports on the Internet that Steam users, once activated, are unable to run the game - it seems the servers have not yet been enabled.
We will deliver keys to your account as soon as we get them, thank for you your patience.
Customer Support Team,
