Help! Can't access wp admin!

A virus appears to have deleted all website files/settings/etc., from within our Network Solutions admin panel, including all backups.

I would like to access/edit our WP blog pages while the problem with Network Solutions continues to be resolved.

Is it possible to access the pages/posts created in WP without logging in using the following address:

http://prayernewengland.org/admin

As of right now, this method above results in an error page. Is there any other way to access the WP admin account?

Help! (And thanks!)
