ITunes won't let me connect to music store

Question

Yesterday I opened iTunes and a window popped up saying something about my iTunes library was damaged. Then all my playlists vanished, along with about 2/3 of the music. I went ahead and uninstalled iTunes 7.0.0 and reinstalled iTunes 7.0.2 and reimported my library. Since reinstalling 7.0.2, iTunes won't connect to the music store. I get a message saying "iTunes could not connect to the iTunes store. Make sure your network connection is active and try again."
Of course, I can get online just opening a webpage. ran a diagnostics and it says a network connection could not be made. I clicked on the help tab and tried to empty the cache, and the dos window had the message: could not flush the DNS resolver cache: Function failed during execution.
I have done all that I know how to do. Any advice would be much appreciated. Thanks!
