I haven't played The Walking Dead since Episode 1, and since then I reformatted my computer. So I've redownloaded to catch up.
When I start the game up, I get to the initial login screen and the game does not progress to the menu. Generally it just stays on the black "The Walking Dead" screen with sounds playing in the background, occasionally it gets as far as "your account does not have a license" and then it returns to the blank screen.
This is the non-Steam version on PC. So far reinstalling, windw-mode, and booting clean have not worked.
