I have seen lots of posts with this particular issue and understand that it is more than likely to do with the prefs.prop however my installation is via DVD and not Steam, so I do not have the steam installation directory and I cannot find any other version of prefs.prop in the game install directory. I have used the TWD_support_data_pc tool and have the zip file but cannot see where to upload it on this forum? so for your reference the install directory is:
C:\Program Files (x86)\Telltale Games\The Walking Dead
and the prefs.prop is located in C:\Users\Gaming PC\Documents\Telltale Games\The Walking Dead
when launching episode 3 there is no sound, no animation just a black screen. there are no dxdiag errors and nothing in the event log. I am able to start the last part of episode 2 without issue and play to the credits on the end of it, but as soon as episode 3 starts the black screen comes back.
Any help would be appreciated
