What is the resolution and frame rate of the video you're editing? What format is it?
Unfortunately, you can't change a project's settings once you've started editing in Premiere Elements. At least technically you can't.
I have heard of people opening the .prel project file in a program like Notepad and manually changing it -- but that comes with a certain amount of risk, so it's up to you if you want to do that.
Again, I'm not sure how your project settings changed. There's not a way to do this mid-project. So I'm not entirely clear why this happened.
