https://mtgox.com/users/forgot - "The requested page was not found on this server".
https://claim.mtgox.com/forgot_login sent me a password reset link once - but the new password still did not work (possible my account was locked because of the failed login attempts). Now it says that it sends me a password reset link but does not and the link sent in the only email I received does not work any more.
i'm having problems too.
I had the same problem. Posted a ticker on support.mtgox.com and eventually it got solved. Guess they are quite busy solving lots of problems.
I have one problem left for them though:
All my balances have been 'withdrawn', but not by me, that's for sure.
All my BTCs and USDs in my account are lost!
And still no reply...
