*EDIT* Try calling and asking to place a phone order. I'm curious to see what they say. Also, I don't forsee a big sell off like you do, there are not that many people that are having issues buying and selling the stock. Those that are having issues very likely do not own a significant enough position to really do much damage to the stock price unless they act like idiots and start bid whacking just to get out.
The majority of the OS (from the last numbers we saw) is locked up in the longs hands and is not going to be sold at these prices. I wouldn't worry about a big sell off.

Have you tried calling in the trade? It costs more, but I think they allow you to make a trade over the phone instead of via the internet.
100% gain is great! You must have bought fairly recently then? Strange that you can't sell.
