http://ratemyserver.net/index.php?page=download_kROLinksIf you know how to use torrents, use the first link ("Sakray 0616 Torrent"). If not, use the second or third one ("Sakray 0616 Full exe").
After downloading and installing that, go to
http://anthemro.com/download/small.php, click on "Main Download Server (Unmetered): AnthemRO Dedicated Download Server", then choose "AnthemRO_Mini_Setup_2007-11-16.exe". If you don't have the background music yet (no BGM folder, or folder is empty), you can download the BGM.zip as well and unpack all of the files (1.mp3, 2.mp3, etc.) into the BGM folder in your RO directory (i.e. C:\Program Files\Gravity\RO).
Install the Mini Setup, go to the RO directory, and start "AnthemPatch.exe". Wait till it's finished, then use AnthemNew.exe to start, choose the test server, play,

, profit!
If you want to use dyes for your characters, try out this client:

main server in order to be able to play on the test server. You can't create accounts on the test server.
If any problems occur (for example while patching something), post here, and we'll try to help you!
