I'm pretty sure I did... It's been so long... Lab coin was only listed on btc-TC right?
Labcoin started out on BTC-TC (atleast I think that was the first trading place for it). It then moved to CryptoStocks when BTC-TC shut down, around 10/17 2013. Trading on CryptoStocks then got halted around 12/01 2013, and in the first days of february 2014 Labcoin got delisted from CryptoStocks.
