nvidia-installer --uninstall      cd /usr/src/linux      make cloneconfig && make dep      cd  /your download directory containing the driver      sh NVIDIA-Linux-x86-1.0-4363.run

If you didn't, please retry one more time. I agree that that you shouldn't go back to older versions. Cheers, It works! I just ignored the error reported and the driver works just fine. One final question: Is there any reason to do the make cloneconfig and make dep everytime I want to install a new driver?

Thanks! Felipe.
