All of my Litecoins are gone!

[a3ro]

I wanted to Litecoin mine. So I signed up in http://ltc.kattare.com/ I started mining with cpuminer. After sometime I had 0.0008 Litecoins (I started mining just an one and half hour before). But when I logged in now to check my stats, all of coins are gone! I had a stale share of 20%, even that is gone. Even accepted shares are gone. When I'm trying to mine now, even if it is accepted, its not showing in my stats. Please help.

Thank you.
