Is there a trick to saving the game because I clicked the save game button and it's nothing but a blank space. There's no hotspot to save. 

Do you have all the game files in the same directory? It should look like this.

On Mac: 

On Windows: 

If this doesn't help, you could try claiming a Steam key and activating the game on there. There's usually no problem with the file system and permissions.

Sorry for the late reply but I claimed the Steam key and play it on there. I'm not sure why the direct file didn't work.
