Hi,
You seem to have tried an awful lot of things in a period that has only 3 feeding days in it.
Have you stopped handling her and left her completely alone aside for essential maintenance?
I would Leave her completely alone for 2 weeks and, at the end of that time offer her a small rat.
Did her previous owner run through how he prepared and offered her the food?
How long do you pre-scent for before offering the prey?
