Curves help

Ok so i have pspx and i used to be able to curves just like everyone else but here lately it has been acting weird and it puts this screen-like white or grey stuff over top of the image. The settings are just like they always have been and i dunno what to do and all the good tutorials have curves so i need to fix it lol. or is it that im totally doing curves wrong? i have trouble figuring out what they mean by point 1 and point 2 but i thought i had it figured out ok.

Example.... it goes from this to  this  the tutorial i used is here i only did the first curves layer.

Thanks =)
