And click 'Map'. Now enter this:

Click 'Map'. And finally, enter this:

Host: mail.godgames.com
IP Address: 80.0.82.178
TTL (Days): 0

And click 'Map' one last time.

Now quit Hostal and if you use OS X: open the folder 'For OS X 10.0-10.1 only' and run Mac OS X Activator (you might want to read the information in the same folder first).
