Yes I did followed what they needed. They paid me out last time as you can see the photo on AskGamblers. I will post it in here again. They paid me out, then when I withdraw all they hold it and needed the documents, which I gave right away. Now its been a month and 6 days to be exact since that.
EDIT to show image

Im pretty sure this will get resolved. If it doesnt their business is over. Theyre probably telling you that its all about red tape etc but it wouldnt surprise me if they need to sort out a bank loan or a fucking mortgage or something to pay you.
Youve got Laudas attention any way (DT1) so its either pay out or close shop. I wish you the best but my gut instinct is that this will be resolved.
And dont gamble with so much damn money

Wow 330 BTC is hell a lot of money. Even for established gambling site. As we can see from screen shot you are not some small amount player thus taking care of your issues should be the priority.
I'm also starting to feel this investigation excuses are just cover story to buy them time and collect the funds from external sources.
Given the amount of accusations against them I'll rather remove them from my signature as well.
Might be good idea to offer them some sort of payment schedule (few smaller payouts on weekly basis or similar).
Hope you'll get your money back.
