Well, my explanation wasn't very good.
Does "C: \ Users \ * username * \ AppData \ LocalLow \ Glitch Pitch \ Idol Manager \" exist?
There are folders for "chash", "data", "Temp", "Unity" and some log files.
Create a new folder in that location.
If you can't find the "Idol Manager" folder, you may need to look elsewhere.
The easiest way is to search the save data folder.
Normally, "Idol Manager \ data \ story_mode \" contains a folder called "* unitname * _ * chashID? *".
(Example: "Future Stars_5504f9f9"
You should be able to find important folders by searching this folder, as the unit name is probably not used elsewhere on your computer.
