How to reinstall Amnesia!

[plutomaniac]

Download the Windows version. You should be prompted to save a .zip file at your computer. Select a location (for example: desktop or documents). Then, using a program such as WinRar, unzip the compressed file you just downloaded. Run setup.exe and the installation wizard to install Amnesia The Dark Descent should appear. After the installation, run the game by double-clicking the desktop icon. At first run, you should be prompted to insert your unique cd key which can be found at the Frictional Game's store, from where you downloaded the .zip file.
