i have photo hype for my ipod touch but now i don't know how to work it.?

[maya]

i had photo hype on my ipod touch and it worked but for some reason now if i go to it, choose a photo, and then i go to "more" (at the bottom right) and then to "Adjust" (in the middle) to add contrast and that stuff, if i click on contrast the bar thing to slide (to add more) will not come up it will only show the "done" and "reset" buttons! so can some one please tell me how to do it!
