Tried using the damn reipatcher on the demo and it doesn't work on that for me either. Really have no clue what the hell is going on. Also realized that the game isn't freezing, it just doesn't load the actual buttons and/or text. The speech bubble on the main menu is still moving. Guess I'm just not meant to actually play this game. Tried it without the reipatcher and got stuck on the world map where I could click on a town to presumably buy shit, but was seemingly stuck there after that. I could buy shit and go back to the tavern screen, but the game never progressed. Dunno if I was supposed to buy something specific and not doing so broke the game, but meh.
what solve for me is change the directory to english so keep all the folder name in english did the trick for me
