Everything seems to be erased. It can be because of something you did accidentally or even a hack/ site defacement. Perhaps your hosting company can help you. Did you contact them?
Do you have a backup of your site? If so, reinstall WordPress and restore from backup and check for any infections.
I am holding with the hosting company now… really hoping they can uninstall this plugin, cause it definitely caused the problem…
no back up that i know of, very new to this =/
If they want, they can restore your site. If you do not have backups, they can help with that too. Make it a habit to keep regular backups as this type of things can happen again (to any site, for a number of reasons). Read:
