Just a stab in the dark, so to speak, but have you had her checked for hypoglycemia? I also had night terrors as a child, was diagnosed with hypoglycemia in my 20's. became diabetic in my early 30's, and even now, when my sugar is low at night (insulin-induced hypoglycemia) I get terrble nightmares. Just a thought. Wish you well, I empathize with your daughter.
