Bummer, I finally got a reply to my ticket, which was an answer to a question that I never asked, so I went to the #MtGox channel on irc.freenode.net and asked 'MagiclTux' (Mark Karpeles) about my disappeared BTCs and USDs. He told me they were stolen because someone hacked my email account. They will 'try' to recover them though and offered me a free yubikey.
No choice, I guess.
