I upgraded to powerdirector 6 from powerdirector 5 and I am wondering if anyone has had this problem that I am having . When I install PD6 it installs just fine. When I cut the computer off and then cut it back on the drivers for my dvd drives will not install so therefore my dvd drives will not work. I have to do a system restore on the computer in order to get the drivers to install for my dvd drives. I have the updated drivers for my drives but they will not work with PD6 installed on my computer. I have tried this 3 times with no success. Tech. support say they have done all they can do to help me but I still cannot resolve this problem. My OS is Windows Vista Ultimate 32 bit. My computer is brand new from Gateway and Cyberlink tells me that PD6 is Vista ready so has any one else had this problem? Thanks Dennis
