I'm not going to spend 10 minutes crawling around under my machine just so I can play one game, then 10 minutes when I'm do so I can play others.
Well clearly Steam isn't going to give me a refund given both the amount of time and hours I have playing it but when a vendor does something so totally half-assed that it makes the game unplayable or a major pain in the ass to do so that's rather idiotic.
