I sent a mail to Jacob Aagard and he said he will sent my error message to webmaster.

Many thanks MarinFan! 

The second book of Marin to complete the repertoire for Black against 1...e5 is out soon.
I think this book and The Ruy Lopez a Guide for Black from Sverre are the best books on the Spanish available on 2007.
I tryed to buy the Marin book from Quality Chess page but it was impossible because I saw this server error page always    :

Server Error in '/' Application.


Runtime Error
Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".


<!-- Web.Config Configuration File -->

<configuration>
    <system.web>
       <customErrors mode="Off"/>
    </system.web>
</configuration>


Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.


<!-- Web.Config Configuration File -->

<configuration>
    <system.web>
       <customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
    </system.web>
</configuration>
