Could you give the exact error message? Usually driver error messages are about burning.
Is this the message:
+"Warning! The registry settings used by the iTunes drivers for importing and burning CDs & DVDs are missing. This can happen as a result of installing other CD burning software. Please reinstall iTunes."+
If so see this link:

It might be worth trying a repair install first. Go to add/remove programs, select iTunes>>Change>>Repair.
Also could you be more specific about what you can't do - is it importing from CDs? Can you add files already on your PC?
