Connection problem under alfresco

[gauth]

Hello to you
I'm using alfreco 5.0 and since then I can't connect anymore because it sends an error message in red "Your authentication information was not recognized or Alfresco may not be currently available."
I even restarted the server and even the service and still nothing.
Even with http://server:8080/alfresco/webdav the login page does not display (not found)
I have 600 GB of data on it which I no longer have access to and I use win server 2008

Alfresco Repository is not starting. Any additional information on the logs?
