Well, taking in regard the specific error you get, i would suggest you check your supported mime types in your server, if you have cpanel you may have a "MIME Types" section,
and you can try and add it there: Extension: .svc, MIME type: application/octet-stream
or with .htaccess AddType application/octet-stream .svc
I am not saying that this is the solution to your problem but it may be something worth checking for.
Hope i helped.
