I get the above error message in device manager when trying to install the driver for my radeon x850. I uninstall the driver in device manager and restart. After restarting i check device manager and it shows the same message. I installed the device drivers from the factory cd aswell as downloaded the latest drivers from the website to noavail. I decided to cut my losses and go for a complete reformat and tried it again....the same results. Ive done a lil work and found this http://www.hauppauge.com/html/winxp_driver_data_invalid.doc Im going to try it and let you all know if it works I hope that its that simple.
