iTunes Store will not open

I just upgraded to iTunes 9 and I'm unable to connect to the iTunes Store.
I keep getting the following error message:
"iTunes could not connect to the iTunes Store.
Make sure your network connection is active and try again."

My network connection is fine, I ran diagonistics and the connection works but is unable to find connection with the "secure link to iTunes Store".
