I have successfully used Slysoft's AnyDVD and CloneDVD for a couple of years. Recently, a newly acquired computer with a Windows 64 bit OS that I bought new (Gateway) would not accept the Clone DVD software, and failed to start up, and went into an automated "repair" mode. After trying to load the CloneDVD software a third time over a three week span, the computer failed to boot up at all, and failed to provide access to the basic setup screens. Had to send machine to Texas for repair. They indicated they had to install an upgrade to the OS (saving all of my files however), but I am quite nervous about trying to load the Clone DVD software. Any history of problems like this?
