cannot login into Yahoo mail

Hey...I am not able to log into my yahoo mail..and yahoo messenger..
I am getting error:
Invalid ID or password.
Please try again.


I tried with my another ID...but same result...But few hours before I was able to login..

Anyone facing similar problem???

SOLVED

I think the problem was from yahoo server side..because the mail login page was also taking too much time to open and verify password.Now it is working fine for me
