iPod help

[Cona]

Ok I tried to put some more songs on my iPod today but when I connected my iPod to my computer it said "The software required for communicating with the iPod is not installed correctly. Please reinstall iTunes to install the iPod's software.". So i deleted iTunes off my computer and reinstalled it again but it keeps giving me the same message every time and it says something about the installation failing half way through. Can anyone help me on this?
