GameGuard servers are being updated. You may see different GameGuard errors or “Game is not available in your country” while the servers are down.
Here’s what NCSoft’s Lani had to say:
Once the update to the GameGuard server is complete the error should go away if you have the full Open Beta 220.127.116.11 update installed.
She also answered the following:
What if you have a CB key that is not activated?
It will most likely not work if it was not activated during closed beta.
There have been reports on the fansites about the gameguard issues all day and I myself witnessed them. Hopes are all will be sorted within the next 3 days. I recommend visiting this topic on Aion RolePLayers forum for a quick overview.
