Please help! with my LiteOn re-writer
 

hey guys
I purchased this re writer (LiteON 40125S 40x12x48x i think) about a year ago, and I got currys to install it all for me, BUT ive had to reboot my computer and i dont wanna pay currys again to do it...
Ive installed Nero (supplied disc) but i dont know what to do now? i think its something to do with the drivers because when i goto Control Panel/System then I right click on LiteON to go to properties and it says there are no drivers installed for this, then there is a buton to click on saying update driver, i dont know how to install the drivers pleasde help!?
I know it says something about copy DOS drivers to floppy on the CD but what is this?
plz help
