Nrc1208: [...] However they wont give me a refund because there is no troubleshooting issue. I am just very unhappy with the purchase.
Any advice?
Think of DRM-free games from GOG or other digital distributors the way you'd think of games you'd buy from a "brick and mortar" store: once you've opened the packaging of one (in this case, downloaded the game), for all the store knows, you could have made copies and distributed them to half the people you know before returning it (which is not to say
you would, but there are definitely plenty of people who
would do this). That's why physical retailers usually have more restrictive return policies for video games, movies and music (usually, if it's been opened, you can only exchange it for another copy of the same title) -- these days, those things are trivially easy to make copies of.
Other big digital distributors, like Steam, require that you have their client installed and running to download, install, and even play their games, so there's much less of an issue with "returning" a game: even if you copy all the files to another location before they remove the game from your account, you won't be able to play that version of the game anyway, since it's no longer in you account. That's not the case with a DRM-free game.
As far as advice goes, I'd say tfishell's above is pretty sound. : )
