Hello. I have a problem with The Great Work. That's what it is: i can play, but i can't save the game - slots are always empty. What's wrong? 
Maybe the game needs administrator privileges to create/modify files, and doesn't have them. Are you using Windows? Do you log on with an administrator account? Have you tried running the game as administrator with right click? Perhaps you checked the portable mode box during installation, but still installed to Program Files or another restricted folder, blocking the game's ability to create save files? Does any of that sound likely and help you to find a solution? If not, could you share any further details?
