What platform are you on?
Have you played the game before?
If your on Windows make sure Boundless is allowed through your firewall and any antivirus is not blocking it.
Make sure Steam is running, your logged in to it (not running Steam in Offline mode) and its up to date (use Steam->Exit to close it to force an update).
