Hi and Welcome!
Normally, there is no additional driver or software needed.
Please explain as exactly as possible, what does not work.
The software that came with the drive is copyrighted, so if you can't get a replacement disc from LG support, then you'd have to buy the software components (Nero Express, Cyberlink Power DVD and Cyberlink Power Producer, IIRC) separately, depending on your needs.
For some tasks covered by the bundled software, there are free alternatives available.
