Yes, if you open up Step1.ascx on/around line 81 is the following code:
 
       <asp:DropDownList ID="ddlCountry" Width="200px"  TabIndex="9" runat="server" OnSelectedIndexChanged="ddlCountry_SelectedIndexChanged" AutoPostBack="True" AppendDataBoundItems="true">
 
Just add visible="false" (highlighted in yellow below) like this:
 
       <asp:DropDownList ID="ddlCountry" Width="200px"  TabIndex="9" runat="server" OnSelectedIndexChanged="ddlCountry_SelectedIndexChanged" AutoPostBack="True" AppendDataBoundItems="true" visible="false">
 
Thanks,
