MichaelFurlong: Woot. Thanks all, I found them in that hidden folder. Seriously, though, could they make it more frustrating!
So, if I want to install the game on my PC (as opposed to my laptop), I will need to copy the save game folders to the same location on my PC (same invisible folder)?
Yes, if you install the game at the default location (C:\Program Files (x86)\GOG.com). But if you install the game at different location (anywhere beside C:\Program Files), for example
C:\GOG.com you can copy and paste your save game straight inside the save game folder of your game. The UAC will have no effect on this and you don't need admin rights to attempt any changes.
Many people suggest to turn off UAC, to avoid nuisance. But for me, i prefer to just changing the installation directory.
