If above steps do not help, then try to repair your Nokia Suite installation, on your Windows desktop, go to Start > Control Panel > Program and Features (Win XP and Vista: Add and Remove Programs) > Nokia Suite > Repair.
If you have a separate Nokia Software Updater application in use, download the latest Nokia SW Updater and install it.
