Are the servers currently down? I have entered my key and according to steam the alpha should be active. But the connection is red in the top right corner and says servers are not available.
You prob tried it to early. They are on right now.
Im currently getting the same and i have the vip key on steam any help apreciated
If the light in the top right is red it means servers are down or otherwise not on. You can only login and play when the light is green. Grey is typically when servers are shutting down.
