Login and creation of accounts working fine

We have solve a little problem with the error messages, nothing important, but now is working well.

We have checked that the google database (Google Base) is working fine, we can add users and check the DB, so we think that we can go on with this DB.

Reading the google docs about GWT we found out that the first call to the database is slow, so it's normal that we need to wait a little time wen we want to connect with the DB the first time. Once that the first connection to the DB has been stablished, it works quick.
