try uninstalling steam from the control pannel on your computer and then reinstalling it and the game. also make sure your computer has the correct drivers and apps to run steam and the games(I.E. direct X, flash player ect.)

First try running Steam using administrator. How? right click steam and it should be there. If it doesn't work, restart your pc completely and don't touch it for 5 mins. Then retry opening Steam or Terraria. If any of those method don't work. Uninstall both programs and re download it. I know it's a hectic, but that's how I do it 3nodding

Some times when a game wont run there is a process you have to go through to empty the game cache of files that have built up. If you're getting an error code i suggest you google how to do this.
