Just as the title says, the download link for the game is broken. Download the Game same thing when trying to download from https://www.soe.com/getthegame/
That link works for me too, but i have had a few outfit mates who have had issues getting the download link to work for some reason.
If you are still running into issues with the page you may want to try using the direct download link to get the game client: https://launch.soe.com/installer/PS2_setup.exe
