Hard-Drive Wiped

[Mister541]

Hello.
I'm not sure if this counts as tech-support; it's more of a purchase problem.

I purchased Amnesia for Mac during the summer of this year and I enjoyed the game.
However, three days ago the hard drive failed and was completely wiped. I am in the process of
re-installing applications when I realized that I did not have the Amnesia installation.

My question is: would I be able to obtain the installation download without having to repurchase the
game?

There are many programs and files I lost, Amnesia being one of them. I would like to have the
chance to play this game again.

Thank you.
