Hi curliejo,


Welcome to the Apple Support Communities!


In your situation I would recommend the steps in the following article for troubleshooting iTunes. It may be necessary to completely remove and reinstall iTunes in this situation. Be sure to remove all of the components with iTunes in the correct order as outlined in the article before installing fresh.
