Again, make sure it is the same tournament you think it is. On the Stats Info dialog, look at the Path column to make sure the tournament that Stats is finding is the same tournament that you are loading from the Game tab. You might have two different files saved with the same name in different folders.
I loaded your tournament. I was prompted to import your league and season, which I did. Then I went to the Players tab and pressed "Add All to DB", and added your players to my database. Then I went to the Stats tab, made sure the Default filter was selected (which won't filter out anything), and press Refresh Tourneys. I see the stats below.
