This will run your KDS CDM-751 smooth, version 4.02 from www.kdsusa.com does not work with Windows XP. This driver/software works great. Unzip this to a folder on the desktop, go in the folder you created, and your on your way to having your cd organizer working smooth again. If your running Windows XP you need to run this driver/software. vesion 4.02 from there web site does not work. So do NOT upgrade from there site or your tower will not work. KDS said they will no longer be updating the software for the tower so save this driver/software if you were lucky enough to find it on this site.
