Can't play and need some help

Make sure your computer has enough free space, that could be a reason why it stops downloading. Also, check if the Windows user you are on has proper write access to that folder, if you're not sure, use the Administrator user.

One thing you can do is have your friend give you the most up to date hero.grf they have along with their neoncube.file, with that the patcher will look and see no new patches and will let you connect.
