I'm thinking about another server you might go to...  try mail.com.  they charge for some services but they may have a free e-mail address for you...    also Hotmail.com.. it's align with MSN and that password thing Microsoft has been pushing around......  Geocities.com was an excellent place to go but now it belongs to Yahoo.com.  they are still around...

1)  Mean time you can try this.....   delete you Yahoo cookie make sure you restart your browser and then try login in again...   the cookie might be corrupted.....

2. try using a a good anti-spyware program.. you might have spyware preventing your port from connecting correctly....

good luck
