Unable to log into online vault - Norton hangs

I had to format some floppy disks today - doing this from the command prompt, as I need to format DD disks!

 

Unfortunately, if the computer is busy formatting the disks, you cannot log into Norton ID safe (online vault).

 

The popup either hangs on 'Opening Vault' - and maybe times out after 5 minutes, or if I wait to start the format until you start seeing the orange and black concentric lines going around, you then just get a grey screen.
