MAJOR HELP NEEDED! Please!

Okay, heres the deal:

My forum: http://megastreams.forumotion.net was hackedd this morning at about 12AM.
I tried the forum backup, but when I went to the dropdown menu, it would not show any dates. The only option was "To Select:" ?

Could somebody help me on backing up my whole forum prior to when it was hacked.
If somebody could, it would be appreciated!

* - I am requesting a response ASAP because I have members waiting on me to have my forum fixed. Please Help as much as possible! |-)

All it says is that the forum is down for maintenance.
