I got this game as a gift.Went to play it, after it said it was installed and I got a stream-error Failed to start game (missing executable). The game file was empty.

Happy to report that there are no technical issues ... but I did miss a key in the first scene and wish to restart the game (in order to find ALL the keys) ... I thought I'd still have the option after all items were found, to continue to key-search, however; the level ended and suddenly the game wished to proceed with or without my consent. Deleting Saved Content and then reinstalling doesn't provide the option to restart, so .... how may I do so? Thanx...
