linuxant driver: warning ?

Hi, I installed the trial linuxant driver for a wlan card in a laptop. The card ended up not being used but when the 4 weeks free trial expired the sytem becam unbootable ( 9.1 ), erroring out with the message "waiting for mandatory device wlan0" rpm -e driverloader rfom within a mounted rescue system reports rpm not installed. Does anyone have any suggestions? TIA F
