Well I stopped to believe to get any of my 450 BTC back. I gave them all information about me, mtgox codes, scan of my ID, everything they wanted. I can't do actually nothing more. Mtgox codes is strong evidence (especially when deposits were made just couple of days before hack). And what is also important I had no open positions, just deposit for interests.

Now I got info from genjix that my account has a lower priority. I've lost my hope, I'm really angry...
