*** SAVING ALL FILES TO DESKTOP IS RECCOMENDED***Once downloaded, assuming you have winrar, open up the finished download file called "client" then click the bottom folder also named "client", on top right click "extraxt to", and then make sure if you have multiple servers/sources on your pc to not overwrite files! then finally open up the unzipped folder scroll down to run wait for it to load then type in any username and password with server ip being Mod-scape.no-ip.biz and there you go :)
