You can't load any games into the game explorer- your games within it will be the ones you've played out in full here.
Game Explorer and PGN files

Mirage, thanks for getting back to me. What I'm trying to do is to use the "computer analysis" of my games. When I click on that a screen opens with a board and at the top it reads "Computer Analysis Demo". But I can't seem to work any of the pieces, or the other functions.
If I want to analyze games that I have already played, how do I do that? Do I somehow play them within that function? Also, since I'm just on a 10 day trial is the functionality disabled? I'm just interested to see what it can do before I sign up for the year. Thanks again for your patience, Frank

When you are looking at your completed game list, click the link that says view. Once you are viewing your game you should have a link for Computer Analysis. Once you click that it will take a little while for the analysis to be complete but when it is, you will have a link to download it. It may be a little different than that; it has been a while since I have used it.
I'm new to the site, but was looking forward to what Game Explorer can do. Am I correct that I can load my own games and have them analyzed?
Also, is there a place I can find out how to load the games? I'm also not familar with FEN / PGN files, what software I need to run them, etc. You can tell I'm really in need of some basics to get me using this app.
Thanks for your help, Frank
