Hrm... i have no idea! as far as i know, none of her content requires an expansion, but clearly you're having a problem... i have all ep's and sp's... according to SimsWiki, this error can happen sometimes... do you have sims2pack installer? http://sims2pack.modthesims2.com/ apparently installing a sim with that can overcome the error? please get back to me on your progress as I definitely want to help here :)
