the thing is nether of these things work unfortunately so i don't know what to do!
Aaah, I'm sorry, I really don't know anymore. :( If even the Ren'Py thing doesn't work, you can try uninstalling it then reinstalling it again, maybe? Looking at your other comments though, perhaps there's something out of place with your os update? There are some games I couldn't open after updating to Sierra too, but these two tricks above have never failed me. :( Aside from them, I really have no other workarounds. I'm so sorry!
don't worry about it and its not just your game i have the same problem with 8 other games and if you cant think of a way to help then don't worry about it its the thought that counts and thanks any way even it it didn't work in the end!
