App Inventor has just been upgraded, you will need to press the reload button in your browser window

Hola … intento entrar a http://code.appinventor.mit.edu/ pero al hacerlo me aparece el siguiente mensaje App Inventor has just been upgraded, you will need to press the reload button in your browser window, de allí no logro pasar, tengo mi aplicación desarrollada desde hace tiempo y ahora no he podido terminarla. Gracias

Did you press F5 ?

That is the reload button.

Yes sure but it’s the same thing, I try, try and nothing.
I can’t enter to http://code.appinventor.mit.edu/?locale=es_ES, so I can’t finish my app

This url is working for me.
