my computer went into emo mode and shot itself, necessitating a reinstall of Windows XP. Now, as noted in the title, I cannot load Fallout 2. I get a message that says "Cannot find the master datafile. Please make sure the Fallout cd is in the drive and that you are running Fallout from the directory you installed it to." I have the US version and it was installed as a Large installation. I'm sure I'm missing some crucial, obvious detail here.
