|Mya, several things could be responsible for what you describe. Perhaps the most basic is just what you allow. Take a look at your 'security' tab in IE and make sure you don't have the Internet Zone set higher than 'Medium' or it'll block. Next thing to look at is your firewall settings. Same sort of deal, too stringent blocks.|
Perhaps more dire (sorta unlikely IMHO) is the fact that you might have been infected by a nasty (virus, worm/trojan, etc.).
