Reply to Stanton FS Open help

I purchased a stanton fs open from musicians friend, to use with the vci-100se and traktor pro, and my mac which is running snow leopard doesnt seem to recognize it at all no matter what ive done. It's a firewire connection, the light on the fs open is turning on when i plug it in so i know its getting power but nothing happens. Is anyone else using fs open with a mac? or anyone have suggestions??? thanks in advance
