Pidgin stopped letting me in with "Incorrect password" error. I have attempted several times to change the password to different values, even trying to change it to the exact same password that worked before. Nothing helps. I am able to login to the "Web ICQ" available on the site, i am able to get into the profile settings on icq.com, the password is valid. It does not consist of any strange characters. Only latin letters and numbers are used.
