Unknown software exception (0x4000015) occurred in the TradePost

Hi,
For two days I have this error when I want to open TradePost. I did some researches over the internet and it said something about firewall. I have disabled my firewall and the error didn’t disappear. Can anyone help me to solve this error ? Why I have this, is something wrong with my Windows 7 ?
Thanks !
