everytime I go on Itunes store my computer freezes, this has only happened since the last update

Hello, Bruce.

Thank you for the question. I see you tried some steps in the article that brought you to the Apple Support Communities. If none of the steps in that article helped resolve the issue, I have included a couple articles that may help with this issue. See the section labeled Blocked by configuration: (Mac OS X/Windows) in the first article.

Hope this helps,
