I have Scottrade too and just talked with them. Jenny from Scottrade said she had no notations in the system that the stock had been deemed worthless, no notations of bankruptcy, etc. and that usually there will be a notation if they truly are putting a zero value on the stock. She suggested I check it after market open and see if the system sets it back to .0001.
Just posting this as an FYI - do your own DD and if anybody finds Markie please let us all know. We'd like to talk with him.
