"But we have no proof that transaction was your, only that you know it. " come on, How I can now that? I can't login to my mtgox.com account , so I can't show you.
I prefer not to stretch the evidence to show something that it couldn't prove. We do not know how you acquire that information or what is really in your mtgox account.
When mtgox.com will let me to login to my account, to take screenshot, I will show you. Also I am not trying to withdraw my BTC from my bitcoin client and run away, until everything is not resolved.
