Yes I can log in, and I moved out the remaining 0.099. I made another 2 accounts, one to which I moved 1 btc and succeeded in withdrawing it too. To 3rd I moved a bigger amount again (very silly of me, I know), and as in the first case, as soon as confirmations hit, a large transaction taking all my credit apart from 0.099b again to the same address. This still doesn't rule out the possibility of a bug, but the whole situation reeks. I sent messages to support from all accounts, no answers at all.
Still hopeful that I will get my coins back, but I guess the probability is not too high.
