i know before if they didn't have a separate listing for the platinum one they would accept it. but i know lately they have been more strict and have been denying items.
might i suggest trading in to gazelle instead? the tiv for KOTOR II is $1 less...but you get 5% bonus for taking amazon gift cards, and also using the code TWEET10 will get you another 5%. so you get 9.90 for a more generous service.
