Hi Mike,
Let's try changing your password and removing the login cookie from your work machine first.
I am sure you know how, so please change your password (don't forget to click Submit).
Go to My Home and then to the bottom of the page. Click on My Cookies in the Maintenance line and then click Expire cookies.
Log back in with your new password. So far so good, right?
When you get home, remove your temporary Internet files and cookies before trying to access here.
Now try logging in. What happens?
