I added a progress bar on my page as shown in the code. But this page started giving me this error:Line: 1429
Error: Sys.ArgumentTypeException: Object of type 'Object' cannot be converted to type 'Array'.
Parameter name: array

This error is associated with script manager. Which ever page I put the script manager, it starts giving me the same error. Please help me to remove this error.
asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
02     <asp:ScriptManager ID="ScriptManager1" runat="server">    </asp:ScriptManager>

Not sure how this concerns Telerik - post questions for ScriptManagar and UpdatePanels in the asp.net Microsoft forums.
