I feel your pain bro, I have lost many a site the same way.
I even lost 2 when the Servedome Hacking took place, luckly i had a week old backup of one,
Still pissed i lost a weeks worth of coding/moding.
Im sure DLow will try and do everything he can to recover your data, Just depends if you was one of the lucky ones, I believe some sites stayed up after the hack but i may be wrong.
