Don't forget the space after the hash.One of the issues I found is that a while ago to help some people access the site, they were advised to add this line
"83.138.155.160 www.p8ntballer-forums.com"
to
"C:\WINDOWS\system32\drivers\etc\hosts"
This line is no longer valid
This file can be opened in notepad and if you see a line like the above referring to P8ntballer all you need to do is put a "#" at the beginning of the line, save the file and restart your browser
