Dear Bitcoin-pro´s,

I really need your help please...
In 2011 I bought some bitcoins via MtGox, I think. After transferring the money via Pay Pal, I received some bitcoins at my account.
Since then I changed my laptop and nearly forgot about them. Recently I thought about them and am wondering how I may find them / recover them???
I downloaded Bitcoin Qt and waited 2 days (slow internet connection) until my account was synchronized.. The wallet is empty... I still have the code I noted when receiving the bitcoins in 2011...
As you see, I am not the pc-crack nor very comfortable with the bitcoin handling...
How may I recover (and sell) my bitcoins??
It´s not a huge amount, nor am I rich ... As we need the cash, I love selling them now, but I just don´t know how??

THX for any help!!

P.S. I think I received some 12 or 13 Bitcoins then...
