FAQ
Isn't using a VPN against the SSA?
Technically, yes, but there are no verified or even reputable reports of Valve taking action against those who use a VPN to simply redeem region-locked keys or unlock released games early; indeed, myself and many other GAFers use VPNs on the odd occasion for these very reasons and haven't encountered any trouble. Valve's issue with VPN usage lies in using it to aid in the circumvention of region-specific pricing on Steam itself.
So my account won't be restricted?
Well, I can't guarantee that Valve won't change its stance, but you'd have to be the unluckiest person in the world to be made example of considering Valve's blind eye over the past several years.
FlyVPN keeps saying the servers are full/won't connect to a server!
If the servers are full, keep trying: sessions only last 20 minutes and upon disconnection users are required to wait another 5 before reconnecting. If you receive an error message when attempting to connect to a server, try a different one as some servers appear to be having issues accepting the protocols FlyVPN uses. Also ensure that the password for the main server you've connected to hasn't changed (see the link above for log-in info).
I'm connected to the VPN. Now what?
Begin the decryption process. You can disable the VPN at this point but you will be required to connect again for the "Pre-load" button to change to "Play", so unless it'll take more than 20 minutes you might as well leave it connected. You can also kill the VPN once you're in-game; although the "Play" button will revert back to "Pre-load", you won't be booted out of the game or anything of the sort. Once you're in, you're in.
