What do you mean you can't redownload ? The game is just a bunch of files what stops you from deleting it and redownloading.
Also I admit I've never seen that error even once before, but I can already tell it's not related to the game in itself.
Whenever I delete and re-download I get the error message again. This has happened multiple times when I've tried to get it back. I assume some kind of file is staying and stopping the game from reinstalling properly, but it just doesn't let me reinstall. I even un-installed the original download file but it still give me the same error message
I'm sorry I won't be able to help. Can't really find much about that error on the web.
All I can find are times where that error happened on the developper side but I have no idea what could cause it on a player side. (because it makes no sense you're still missing files after deleting and redownloading)
Only reason I can see is you're on phone and there's a problem with the local storage (cuz rpg maker stores some stuff like the saves here) and if that is the case you might want to download JoyPlay and emulate the pc version instead which should make it so it won't happen again.
I just figured out that all I had to do was clear the cache and data, and I was able to get the game back super relieved about that! I’m definitely going to install JoyPlay as well, just to make things smoother. By the way, you’re seriously the GOAT, Faust.
