[Error] Really big problem with my game

Hello once again. I've encountered something really awful. whenever i open my game to try and playtest it, i get the error messages shown below.
TypeError, "incompatible marshal file format (can't be read) n\tformat
version 4.8 required: 0.0 given", ("Section049:646: in oldload",
"Section049:646:in load"", "Section247:8:in load_data",
Section 247:8.in .pb SafeLoad", "Section247:78: in pbSetUpSystem
Section 247:137)

this one is always followed by this script error.

Script 'PSystem_System' line 85: TypeError occurred.
Cannot convert Fixnum into String
OK


The thing is, I haven't changed that part of the script at all. in fact, the last time i played the game, it worked fine. i even took the script from another game and copied and pasted it and it still worked. i dont get it at all. what can i do to fix it?

Delete your save file

how do i do that without entering the playtest

If you are using version 19 of essentials, it'll be located in:
C:\Users\[Computer Name]\AppData\Roaming\[Project Name]

If you are using a version before 19, it'll be found in:
C:\Users\[Computer Name]\Saved Games\[Project Name]

enter the [Project Name] Folder and delete "Game.rxdata"

it didnt work. the errors still showed up.

the answer is "I don't have answers" as you have supplied insuficient information on what you did to the scripts prior to loading the game.

You added something
It Broke
I'm in the dark as to what you added.

"incompatible marshal file format" usually means you borked with save data loading/Saving, and that is a delicate and complex area to bork with. I should know, I've borked with Save Data stuff before.

Your options are as followed:
A) Remove whatever you added and revert that portion of code to default of whatever essentials you are using
B) Give detailed info on what you added Where and What Version of Essentials you are using
C) Give Up
you're better off with with A but I know you're gonna go with option B. only a villains go for Option C, and you aren't a villain. just a noob. A await

i didnt add anything

Seeing as I had to dig for this info do me a simple solid. open up the project folder, open up "Data" and take a screen shot with "Constants.rxdata" highlighted like the screenshot below



if that file doesn't exist, that's your problem. if it does I'm lost and unable to help

unfortunately, the file does exist, meaning that i assume you cant help me. i really appreciate all the help though, thank you a bunch. im sure ill fix it one day. itll be fine.

oh ok! i replaced it with another one that i had backed up and it worked!!! thank u sm!!!
