for the v.55 download, it leads you to Megaupload. Just type in the code in the box (next to the big MEGAUPLOAD) then wait 45 sec. After that, it will show the download button.
For the client, it leads you to Rapidshare. Simply click Free User and wait a couple of seconds. Download button will appear.
NOTE: I'd recommend downloading the Non-DC client. You can find it in General Chat in the forums. Title of thread is "[Fixed Client][No random disconnections]".
DXWnd host is pretty straightforward.
