The cdm-751 (KDS CD ORANIZER): If your trying to get the tower to work with version 4.20 from www.kdsusa.com your ready to shoot someone by now. Couldn't get any other driver/software to work on windowsXP. This software did the trick after looking for 30 days for a driver. KDS does not offer any more support for this product so we are on our own. v3.0 v4.0 seem to work but the new 4.20 from KDS does not. So save this version of v3.0 as soon as you get the tower working. You may never see this driver on the web again. The company bailed out on KDS that updates there software for the tower. And the only thing left for the public to download is v4.20 from (WWW.KDSUSA.COM)AND IT'S USELESS! And was told there will be no more updates for this unit. Good luck! WindowsXP User
