if you go to tournaments, results, then data view, you will see all of the tourneys. 

then, if you click on one of those tourneys at the top, the hands will be shown in the pane at the bottom. it will probably only show the last 100 so you will have to click the all hands button. 

then if you select all hands, and then right click and go replay all hands, it will load all of the hands into the HEM replayer. 

hope you can follow that, i am at work so i dont have HEM in front of me.
