Can someone please help me out with something related to XCP?

I was given some shares of a stock/asset on Counterparty, to my local BTC address. I just created my XCP account as well to try and see how I can access those shares directly (for trading, keeping up with them, etc.). I'm completely lost as to what I need to do.

I have full control over the address in question (that is linked to the shares), so if I need to sign a message in the client or something that's not an issue. I'm just confused as to what I should be doing right now.

Thanks guys!
