Cache files are stored on your PC so Sea of Stars and other apps can launch quicker. However, if there was a problem when Sea of Stars closed last time, and cache files got corrupted, you must delete them manually. Don’t worry. They will regenerate the next time you run the game.

  1. Use the Windows Key + shortcut to open the Run dialog, type %localappdata%, and hit OK.

  • 🔁 Reinstall the game: Uninstall Sea of Stars and delete all files and folders related to the game. Restart your PC and perform a clean game installation.
