[L&O] How do I find the other 6th episodes
 

I bought the Telltale LawAndOrder Legacies for my PC but after playing episode (1) I cannot for the life of me figure out how to download or even find the way to play the other episode. I just have the option to keep replaying episode 1 over & over. I paid $19.99 and I have no instructions on how to play other games. Should not be this hard? Please someone Help me learn to find Episodes? TYIA:D
