The game show this error every time I try to run it, how can I fix it? I know that's about a .iwd file in /main folder that is broken, but I don't know where can I download it to fix the error!

Run Steam integrity check, .iwds might be corrupt

or redownload the game

or find the 3_cursor.iwi file on the Internet and put it into iw_00.iwd/images(open it with winrar for example)

Oh, thanks! I made it all, now I know that all my entire /main folder is corrupted, and I have to redownload the game. Thanks for the help!

Good to know.

Locked.
