what is the cause of 'System.IO.IsolatedStorage.IsolatedStorageException'?

Exceptions: A first chance exception of type 'System.IO.FileNotFoundException' occurred in mscorlib.dll A first chance exception of type 'System.IO.IsolatedStorage.IsolatedStorageException' occurred in mscorlib.dll

    public static IsolatedStorageSettings settings = IsolatedStorageSettings.ApplicationSettings;

    private void GetScoreData()
    {
        if (settings.Contains(dataItem2.Name))
        {
            this.textBlock2.Text = settings[dataItem2.Name].ToString();
        }
        else 
        {
            settings.Add(dataItem2.Name, "N/A");
            this.textBlock2.Text = "N/A";
        }
        settings.Save();
    }

now in the other page

i am updating its value by doing this

ScorePage.settings["MyKey"] = moves.ToString();

so everytime i restart my emulator and run my project this exception comes. any reason why?

The isolated storage in the emulator is not persisted after you close it.

Reference: Windows Phone Emulator: (see features)

Isolated storage is available while the emulator is running. Data in isolated storage does not persist after the emulator closes. This includes files stored in a local database, as these files reside in isolated storage. I suggest you to use site settings over application settings. One more thing, dont worry the windows phone is persistent.(only the emulator is not!)

After restarting the emulator (or reinstallign the app), the contents on IsolatedStorage will be deleted. If you're trying to update a setting, first check that the key exists.

Showing the line where the exception occurs and the exact text of the exception will also help with identifying the issue.
