I have been trying to go to the home page since last week and keep getting an error message that reads itunes stor temp unavailable is anyone else getting this error
By way of experiment, perhaps try updating your Windows Root certificates.
In Windows Update, click the "Custom" button. Under Optional, Software select the Update for Root certificates October 2010 (KB931125). Install that one.
After that quit and restart iTunes and try going to the Store again. Any better luck this time?
