1, When updating image and game disk with super client, CCBoot will modify the image and game disk directly. So if you update image or game disk on multiple client PC's at the same time, it will lead to data written conflict which may damage the image and game data. So please use super client on one client PC at the same time.
2, Please check if the option "keep write-back" is checked in the client properties. If so, please uncheck it.
