You should not need drivers for it. I installed a new cdrw and worked without any disc's been loaded. click here if you are having problems click on the contact us and ask them but like the above I suspect Nero is playing up.
Did you get NERO with the Drive? if not that is why it will not work. If it's a old version of NERO it may not recognise the Drive. The drivers that make the CD-rom work as a reader are MSCDEX part of windows, the only other drivers that are used are included with programs Like NERO that allow the software to talk to the Drive
