I get an authorization failure when trying to login Contact your local technical group it may be that your account is disabled, the most likely cause is that you have not changed your password having been asked 6 times. You may need to goto your faculy's techical department to get some issues resolved. Unfortunately this happens quite a lot and sadly there is nothing you can do about it. Sometimes word and other programs do make an automatic backup of your files and in most cases this is the only method of retrieving any work since your last save. Though it is possible to kill the application that has crashed the best way of recovering is to shutdown and reboot the computer.
Some applications can cause the machine to crash due to bad programming.
If you get a 'blue screen of death' then you will not be able to continue working and will have to switch off the machine. Also note that as you cannot logout properly when this happens you will not be able to login again for approx 10 minutes. A registration password is randomly generated by the program Selfreg. Note however that when you change your password for any service, it will change for that service alone. It is therefore very important that you keep a written note of your registration password.
