Exception loading saved data

Windows UWP
1

Hi,

I’m having a problem loading data on a Windows Store app. Here’s a snippet of my code to load:

if (container.FileExists(ProgressFileName))
{
    try
    {
        Stream stream = container.OpenFile(ProgressFileName, FileMode.Open, FileAccess.Read);

This throws the following exception:

Additional information: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))

The code to write to the file is as follows (and executes without any exceptions):

  StorageContainer container = mDevice.EndOpenContainer(result);
  if (container != null)
  {
    if (container.FileExists(ProgressFileName))
    {
      container.DeleteFile(ProgressFileName);
      //TODO Backup previous file and put it back in case of error saving
    }
     
    Stream stream = container.CreateFile(ProgressFileName);
    XmlSerializer serializer = new XmlSerializer(typeof(SaveGameData));
     
    serializer.Serialize(stream, SavedProgress);
     
    stream.Flush();
    stream.Dispose();
    container.Dispose();
  }

Am I missing something?

Thank you.
