Midnight Mansion HD: Episode 1 download link (beta 1)

[Semi-Native]

I can't even get a mansion to start. I keep getting the error message about the mansion has been modified, download a fresh copy. I've downloaded the game 3 times and haven't touched it in any way. And I can't open a mansion using

Open Mansion

because I haven't purchased the game.

I'm using OS 10.5.8
