Does anyone know how to get documents to open in Aguascalientes Public Archive?

Hi Everyone,

Does anyone know how to open the documents to view in this public archive of Aguascalientes? I want to look at a 3 page document of a esclavo that was bought by Fernando De La Campa y Cos in 1724. In the past, I did view it but I didn't save the documents. Now when I want to view it, it doesn't open.

To use Publica Archive of Aguascalientes:

http://sigue.aguascalientes.gob.mx/

Usuario: sigue.publica

Clave: publica

Once you log in click on the "SGG Archivo Historico"

Then click the drop down menu of "Tipo Documental"

I chose the topic "Compraventa Esclavo"

And on pages 301 - 400 of 488 near the bottom under the head title "Contratantes" is the transaction by Fernando De La Campa y Coz

I clicked on that and it tries to open but never does. Before in the past it did, but now when I want to read that document in more detail it won't open.

I hope one of you can help out and thank you if you try to help.
