We have the entry upload replaced here on our new host and working well.
You will see a new password page, the password is the same as the old page, just no need for a username.
If you search your email for the old username ( firstname.lastname@example.org ) you will see the password you need when it was sent to you.
The password was also emailed to the INPA list (on 5/30/2011) as well.
If you need to request a password please use this FORM.
