The Mt.Gox Account recovery service has now started, please go to
https://claim.mtgox.comand enter as many data (bank name of deposits or withdraws, last account balance, ...) as you have in order to claim your account.
And please, include lowercase and uppercase letters as well as some numbers and symbols.
And just to make sure, make it 15-20 characters long.
Heh... Here is what I got - The password for this account is invalid, or this account is not currently under claim process.
Password is 101% valid (well, at least it exact to one I used to register). So here it go - mtgox.com just trying to scam people away to cover their asses.
