update errors

Hello everyone: I'm currently running SuSE 9.1 professional in 64-bit mode on an AMD Athlon 64 on an Asus K8V Deluxe motherboard. When I try to upgrade the packages / patches using YOU, three of the major components report error messages during the 'install' portion of the upgrade (the download seems to go OK). The three main components are: the new linux SuSE kernel 2.6.5-7.95 (I think) the Xfree window manager and the KDE base packages. Anyone had similar problems and, more importantly, is there a fix. Cheers, Mike
