Do you have "systemback" ? If so please run it to restore back to working order.
If not have you run a system backup at some point?

Again sorry this has happened, this is the first time this has happened to myself, ( so i need to know why.
EDIT: Another approach is to open "Software & Updates" goto the "Additional drivers" TAB , & select the listed driver again select "Revert" & run the update.
