Check if your antivirus is blocking access to the game.

Also check if your steam client's up-to-date. If it isn't, and it still occur, try reinstalling Steam (by deleting Steam files and NOT steamapps files so you won't have to deal with reinstalling most of your games that takes time.)

Still isn't working? Reinstall the game.

If all else fail, try checking out this thread.

Mine fixed just by restarting the steam client.
