Some kitties don't like big changes. Consider changing the litter back to what she WAS using before.
If that doesn't bring her back to the box, put her box in the corner she's using, until she's using the box again...then move the box slowly to where you want it. And if that fails, take her to the vet...she might have a health issue of her own. Kitties who feel pain when they urinate will start to associate it with their litter box...and go elsewhere.
We use Feline Pine. The cats love it and it doesn't smell bad...it doesn't clump, but it does clean up easily. Cedar has a pretty distinctive smell...she might not like it.
Best of luck!
