I decided to give Rollback Rx another go now that there is a new version out. I have done this before without any problems: 1. Uninstalled FirstdefenseISR 2. Installed Rollback but at the end of installation Rollback gives an error message telling me it cant write MBR. Rollback´s shedserv.exe (not sure I remember the file name right) loads on reboot but no tray icon. When I try to start rollback icon from the start meny it starts but closes down immediately. When I try to start the console from start meny it tells me Rollback is uninstalled. Any ideas? Would a uninstall/reboot a fdisk /MBR command from DOS and a new install help? or has anyone else encountered this problem?
