Can`t add compilation to TestFlight

Hi.


I have a problem. I send my compilation with application Loader but when i try to add it to TestFlight i have an error.


Smoething like

"There was an error processing your request. Retry."

(Se ha producido un error al procesar tu solicitud. Vuelve a intentarlo.)


Is a generic error i don´t know whats the problem.


Any help?


Thanks.
