this is the solution I use:
download the Opera web browser and use it to login to the webpage:
http://www.opera.com/
the reason is that it has a built in function to block javascripts, or the popup that stops IE from getting any further when you get the message that your id is invalid or whatever.
another way is using the password manager. when you type in id/pass the password manager will pop up asking if you wanna save the pass or not. at the same time the message saying your acc is invalid wil pop up. click confirm on the popup and cancel on the save pass query and it will continue to log in.
hope this'll help
