Hey Kelly,

Welcome to the board.  I started out with a TDAmeritrade account also.  Owned shares in another company with the same problem that was chilled about a year after I bought my shares.  I could sell but, couldn't buy back.  I opened another account with Fidelity.  Heard others mention Scotttrade.  Fidelity charges 7.99/trade.

IMO TDAmeritrade is probably one of the worst brokers if you want to trade penny stocks.
