CMC & CC121 user settings gone!!

Started Cubase today & discovered all of my user settings for all my CMC controllers & the CC121 have been replaced by the default settings. Does anyone know how I can recover them, say by grabbing a file from C7.5 (which has the same user settings) & putting it in the C8 folder?

In other words does anyone know what file(s) contains the user settings for the CMC series?
