Invalid publishSettings file when trying to connect to debug azure

In order to connect and debug a node.js program on Azure websites, I need to use a publishSettings file. When I download one from the Azure management console, and try to import it I get the following:

    c:\>azure account import "MyServices.azurewebsites.net.PublishSettings"
    info:    Executing command account import
    error:   Invalid publishSettings file. Use "azure account download" to download publishing credentials.
    info:    Error information has been recorded to azure.err
    error:   account import command failed

When I try to use the "azure account download" command, it opens a browser window, and then gives me a 500 error from the azure management system.

Same things happen when I try to do this from the Azure PowerShell commands.

Thanks
