I just noticed that was for IE, so if anyone has Internet Explorer, try the last quotes on my last post. I'm researching FF now.
Edit ;
It seems like most people with FF are having this problem. The first thing to do is check to see if you have cookies 'expire' at the end of each session. If not, then it looks like you'd have to go delete all cookies and see if that helped. There's another way, but it involves opening some folder, making a backup of a cookie agent and then deleting the agent, seeing if that helps? I've never heard of that, so I'm not going to try it.
Edit;
I cleared my cookies and then tried again and it worked. I would suggest writing all your passwords beforehand because clearing cookies often clears any autosaved passwords.
