Error: Cannot create folder "_vti_pvt".
Setting Password

I cannot see my index.htm page. It looks like it's empty as well.
Cannot contact host as he has left and abondanded me. I'm trying to move
the sites to a new host, but they need root pw and SSh enabled. Have no
idea as of what to do next.
thanks,
