I updated my computer from Vista to Windowa 7 about a month ago. Every program worked then, but after installation I had problems with some programs connect with the internet. Internet Explorer, Windows Live Messenger, and Yahoo Messenger don't conntect. And iTunes doesn't connect online also to its store or able to authorize it. Also video's won't upload to YouTube as well. I am using Firefox which works along with Opera and AIM. That is all I know. THe Tech support from my college never heard of the problem so I thought I should post. I have seen somewhat similar problem but nothing exactly.
