I am trying to run Psychonauts. I have all the ncfs, and the common folder, everything. But when i try to run the game I get the error: "You do not have a valid Steam subscription for this application [AppId=3830]." I have never had this error. What do I do?? Please help! EDIT: Nevermind. I bought it. Thanks for all your help. I appreciate the nothing that was done.
