Please try uninstalling the game. Your save games should remain intact. Once the Walking Dead is completely uninstalled, navigate to the Playstation Store and do a search for 'Walking Dead'. One of the top results will be for Episode 1. Select this and you will be taken to the Episode 1 page. The episode should be listed here as already purchased, and selecting it again should allow you to re-install Episode 1. Since you own the Season Pass, you will prompted to download 3 items, the Episode 1 demo, the unlock key, and the theme. Once installation is complete, you can reinstall the other episodes.
This issue has been reported by users who originally played Episode 1 for free as a PS+ member, then allowed their subscription to Plus to expire, which invalidated the unlock key. Even if the Season Pass was purchased, Episode 1 was still installed using a no longer valid unlock key, forcing a reinstall to continue playing.
