Open HxD Select warrock.exe find webid if it's there you should see normal ip that connects to another pserver and you change it to yours hamachi(if with ur friends) or local ip(if it's only you),then pack it into a .zip and upload it to like mega.nz and when done go to C:\htdocs and open download.php with like notepad++ and you need to change name and link for downloading,then you need to invite friends and that's it. have fun
