If you are unable to save or load the Steam version of "Atelier Yumia: The Alchemist of Memories & the Envisioned Land," please try the following steps:

1. Log in to Windows with an account with administrator privileges

Additionally, try launching the game as an administrator by right-clicking the Steam Client or the game's executable file (.exe) and selecting "Run as administrator."

2. Check the sharing settings for Documents folder

If your "Documents" folder is shared via services such as OneDrive or Dropbox, it may prevent the game from functioning properly. Please follow the steps below to disable or uninstall these services and see if the issue is resolved.

Note: Even if you have not installed or configured these settings yourself, in many cases the Documents folder is shared via OneDrive by default.

Note: The following instructions use OneDrive as an example. If you use other file-sharing services, please refer to their official websites for instructions on how to disable sharing.

(1) Open the save data folder for this game, which is located in the following path within your Documents folder.

(2) If the text "OneDrive" appears between your user name and "Documents" in the folder path, unlink or uninstall OneDrive.

For instructions on how to unlink or uninstall it, please refer to the official Microsoft support page: "Turn off, disable, or uninstall OneDrive."

Note: If there is no text between your user name and "Documents," proceed to the next step.

(3) After unlinking or uninstalling OneDrive, reopen the save data folder and confirm that the folder path no longer contains the text "OneDrive."

Note: If the text "OneDrive" still appears in the folder path, or if you are unsure how to unlink or uninstall OneDrive, please contact Microsoft support for assistance.

3. Confirm that read/write permissions are properly set for files and folders

Open the Properties window of your save data file or the folder where your save data is stored, and confirm that access permissions are correctly configured on the "Security" tab.
