Ok so everything works for me in the Somua tutorial except when I go to save the new host file, it simply won't let me overwrite the old host file. Whenever I click Save, it takes me to the Save As screen and how I want to save it, what should I do?
I assume you're using notepad, right? Then choose "All files (*.*)" in "Save as type" dialog.
But I think it would be easier to use sk's hosts patcher.
