>The missing double slash was a typo when I posted. I am using the @ so the double slashes are added for me and the value of saveName is while in debug mode where I copied it from. I have found the issue to be with the file name as I changed it and it no longer was a problem. I don't undersand why though since I have created many records using that same file name creating code. The exception thrown is the "NotSupportedException" of File.Create(string) method.

Tim,
I added Path.Combine to your code as an example how the Path class can be used

string saveName = Path.Combine(this.FileQueueDataPath, string.Format("Spot_{0}.xml", fileID);
FileStream stream = null;
try
{
     stream = File.Create(saveName);
     // everthing else left out
}

public string FileQueueDataPath
{
     get
     {
          if (_queueDataPath == "")
          {					
               _queueDataPath = Path.Combine(TrackerSettings.Instance.AppDirectory, TrackerSettings.Instance.QueueDirectory);
          }
          return _queueDataPath;
     }
}

Settings File contains:
public string AppDirectory		= @"C:\DevelopCSharp\TrackerClientTemp";
public string QueueDirectory		= @"\Database\SpotQueue";

public string CreateFileID()
{
    DateTime now = DateTime.Now;
    if (TrackerSettings.Instance.UseUtcFileId)
        now = now.ToUniversalTime();

    string fileID = now.Month.ToString() + "-" + now.Day.ToString() + "-" + now.Year.ToString() + "(";
    fileID += now.Hour.ToString() + ":" + now.Minute.ToString() + ":" + now.Second.ToString() + ")";

    return fileID;
}

You could also use File.Exist() to find out if the file exists
