I'm not entirely sure what the issue is. I've downloaded the game 3 times now and it won't save properly. Even on my laptop it does the same thing. downloads the whole file but the gog icon doesn't show up. it'll try to load it then give me a error.

Are you using the gog downloader program or just downloading it through the browser? Also do you have a firewall running whilst downloading this?

I'm using the gog downloader. And no to the whilst. I re-downloaded it for the 10th time and It finally worked. But there was no gog icon on it. Kinda weird? Thanks for your help though!
