UpdatePanel and Timer not working

I have this code:

<form id="form1" runat="server">
<div>
    <asp:ScriptManager ID="ScriptManager1" runat="server">
        </asp:ScriptManager>
    <asp:Timer ID="Timer1" runat="server" Interval="1000" OnTick="TickEvent"></asp:Timer>
    <asp:UpdateProgress ID="UpdateProgress1" runat="server">
        <ProgressTemplate>
            <img src="http://jimpunk.net/Loading/wp-content/uploads/loading18.gif" />
        </ProgressTemplate>
    </asp:UpdateProgress>
    <asp:UpdatePanel ID="UpdatePanel1" runat="server">
        <Triggers>
            <asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick" />
        </Triggers>
        <ContentTemplate>
            <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
        </ContentTemplate>
    </asp:UpdatePanel>
</div>
</form>

Codebehind code:

protected void TickEvent(object sender, EventArgs e)
{
    Label1.Text = DateTime.Now.ToString();
}

But when I run the page, the time doesn't update and the progresspanel doesn't show. Can any one help?

I solved it by recopying all the scripts files to Scripts folder
