Help Us!!

Now...I'm trying to be more useful than ever with doing what I like and what I can do. I'm running the business batik with my boyfriend since January this year. You can check our online shop, kingandqueenboutique.blogspot.com. Actually, we wanted to try use OpenCart, but when I call the server using filezilla client, it could not connected with the hosting server. Can anyone help us? We were really confused... Thanks :)
