I would try a good clean install of the driver and see if that helps.
Have the driver you want to install downloaded.
Run DDU from wagnardsoft dot com, from safe mode with the Internet disabled. Just unplug or turn off the router or modem is fine.
Restart after running DDU to normal but still have the Internet disabled.
Then install the driver again don't use express settings. Use Factory Reset and that should get you going again.
Good Luck!
