thanks for the fast reply!
do you mean by adding it to my library via the store? because if so, then i can't because its not available in my country. any workaround on that one?
so i bought the game 3 years ago (Part 2 V.1.0) and just realised i had a steam key for it, if it try to activate it, steam says i need the original game first for it to activate it, any way for fix that?
