Can someone help, can't Login to Yahoo! Mail Beta for last 3 day?

This is the error message window I have received for the last 3 days:

Yahoo! Mail Beta experienced a login error: LoginError

name:Reference Error

message: sp is not defined

line Number: 110

file name: http://us.js2.yimg.com/us.js.yimg.com/li...

I use and have used Firefox1.5.0.8 with this account for sometime. It just stopped working. Thank You - Melody W

Yahoo! Mail's been having some problems recently.

If you still can't get in, you may want to try deleting your cache, closing your browser, re-opening your browser and trying again.

And if that doesn't work, try deleting cookies, closing and re-opening the browser.

Hope this helps!
