Hi there! Did you start the game using an old save? Or did you start from scratch? We have posted a save file on Patreon so that you can start the game from the new scenes. If you have already talked to the person (trigger) who tells you to go see the fireflies at night, the first scene should be on a night without rain.
The HQ and Bus Station scenes are scripted so you should be able to see them with the flow of the game, the trigger for those scenes is Ellie in the park at night, after that you should go to sleep and the next day you should leave the room through the door and not through the map, the new scene will appear, you cannot travel to HQ and Bus Station with it in this version, but you should be able to see the scenes.
For the black screen problem we have a solution
Black screen problem
1) Find your GameData in Documents/Gatolobo.
2) Back up your GameData.PHD file (we recommend the way the issue kicks in, you may be able to recover your saves)
3) Open Peach Hills Division Game and start a new game. Pause it with ESC
4) Without closing the game, press ALT+TAB to open your Windows Explorer with Documents/GatoLobo open. Restore your save files.
5) Return to the game. You can return to the main menu.
6) Load the game.
This method can restore your saved files
however please note that we will be releasing a patch between today and tomorrow where the black screen is solved among other things, you can contact us through discord to check more details.
