Thanks all for your replies. I was going to "cash out" most of my bitcoins. I thought, I'd just money transfer the whole thing away. But later found out that I can only do that at 1000 dollars a day. I've opened 7 calls with mtgox, but everyone of them gets closed automagicly, without any human looking at them. They have some other issue and assume every trouble-tickets is logged because of that.
I do hope someone here knows an other e-mail address or something so I can contact them more directly. Please PM me if you do.
