Need help with Extended Pitch Editor

I have the one from here: http://z-server.game.coocan.jp/utau/utautop.html#pitedit

The problem is, once I set my pitches in place and press OK, nothing happens.. no pitches are added in or anything. I think I may be doing something wrong and it's not just my computer, because I tried on two different computers with the same results.

Does anyone have any advice on what I can try, or similar experiences?
Thank you!

Oh I see, I fixed it now! If anyone else had my problem, apparently I was on Mode1, and that doesn't allow pitches with this editor I don't think? Switching the mode to Mode2 made them work and appear!
