The last version I have installed is r31.1 and I've tried updating it to this but whenever I'd try to play I get Failed to load: img/faces/p-zbrow1.png It's also happened with p-zbrow3.png and p-zbrow4.png
Your save files are from too many versions back and isn't compatible anymore. If you're on desktop though, you can navigate to the folder with the missing file, and put a dummy file in there to trick the game into thinking everything's fine. Then just save your game and it should work.
