• You will get one or more XML files. Open the most recent file in wordpad. Lines 14 – 21 have a simple score on each line with XML tags.Change the score you want to be displayed.
• Save that file after editing the value if windows doesn’t allow you to save that file check whether UAC is turn off if not turn UAC off.
