I wouldn't sweat it. Maybe just give her a little more time to adjust. Let her get another meal in her, wait a couple days for her to digest and try again. She will adjust and become comfortable with her new home, as well as with her new keepers. Don't feel the need to rush it (I know, it's hard, you want to enjoy your new snake), you've got many years ahead with your new animal.
Is her enclosure set up with more than one hide? Does she have plenty of security in her new enclosure? Making sure she feels safe will help her adjust.
