well it's been over 8 hours now & I haven't heard anything, not that I was expecting to of course & I'm still unable to withdraw my slowly dwindling Net Value balance now at $350.99 or liquidate or do anything at all on my Bitcoinica account & yes a base price of $4,389,544,719,889,099,776 hmmm - a little steep maybe 
Try this:
Buy 0.03 ฿, and the liquidate again.
tried multiple times on different browsers - doesn't work, says Insufficient Margin & still unable to liquidate this false position or do anything to free up my Net Value for withdrawal
