Hi, running a Dell Inspiron with Win XP. Up until today been very trouble free but now cannot run cd or DVD in drive. Drive is NEC DVD +RW ND 3530A and I get the following message "Windows successfully loaded the device driver for this hardware but cannot find the hardware device. (Code 41)". All worked fine yesterday, started today and cannot play anything through drive. I have not disconnected anything or moved anything so any ideas gratefully recieved. TIA.
