Might just play it safe and stick with the official download. It's not that hard to install anyway. (And I think the torrent was Mac only...)
Just follow these instructions and you should be good to go:
1. Download the OpenGFX, OpenMSX and OpenSFX .zip folders
2. Download and run the installer
3. Once the installer is complete, paste the extracted OpenGFX, OpenMSX and OpenSFX folders into the "baseset" folder of the install directory.
4. Run "openttd.exe"
