Hi Nikki,
Sorry for the problems you're having. You made a couple of mistakes, besides the obvious of not checking that the floor was flat to start. You should not install tile backer board over hardwood or plank substrates.
It's very odd that the backer cracked. Did you spread thinset under the backer, tape the joints? That hardwood must be very loose.
What type of room is this? Going from ceramic to a laminate is kinda extreme, you sure you wanna do that?
