I've read posts on other boards that state they are going to do the same thing as you. Appears Scottrade is not very helpful in transferring the stock to another broker and of course want money. I'd say just stop using it, and open another with some other broker. You also don't want to get stuck with not being able to buy more CPRK along the way. This has been a problem for some while flipping other stocks.
I closed my account with Scott a few months back when many of the stocks I was trading appeared on their long list of stocks with clearing restrictions.
