I went through some hoops. Apparently for some reason the script provided didn't follow the instruction... the script asked for 5.1.19 but PoL assigned 1.7.11. Anyway, I ended up creating a 32bit virtual disk + manually did some of the steps of the script. Due to an Steam update, it won't work on 1.5.19 or any previous WINE versions afaik, I had to do some extra questionable steps to make it work.
End result My System:
Linux Mint 16 (petra) x64 Running 32bit Wine 1.5.19 NVidia drivers: 331.38
