Hi rovers.
Use Ctrl-alt-delete to open Task Manager, and look for these processes
mbssm32.exe
mbsrm32.exe
If there stop them.
You will need to reboot your computer into Safe Mode for the next steps. N.B. It would be a good idea for you to print these instructions, as you will not have access to the internet.
Important: If you have an 'always on' connection to the internet, physically disconnect that connection until you are finished with Safe Mode and have rebooted back into normal mode.
Boot to Safe Mode. To do this:
Restart your computer.
Continually tap the F8 button as your computer is booting (a menu appears).
Use up-arrow key to select Safe Mode and press Enter.
