Jeremy, The marblesound website has been down for a while now unfortunately. We're told it will be back soon, but it's hard to know when that may be. In the meantime, I might suggest using MIDI Yoke from http://www.midiox.com. Note, if you choose to go this route, be sure to click the ";midi yoke"; link in the left column as it's not the same software as midiOx. Also, be sure to follow their well-written installation tutorial to ensure proper installation.
