I can  solve the problem.

Create another google account, and onother Paypal account.

When fill the fields i use simple stuff for example: name: prueba.nombre.tsi2 gmail.com , passwprd: passtwordtest.

The error in the accounts of sandbox that I created at the start was in error state for that. 

And create a facilitor user with 999 of founds.
