Could not find stored procedure - SQLDataSource

Question

Other similar questions haven't really been relevant to my problem so I'm making a new one...

<asp:SqlDataSource ID="SqlDataSource2"  runat="server" ConnectionString="<%$ ConnectionStrings:CatalogosConnectionString %>" 
                          InsertCommand="dbo.GRM_Novo_Catalogo" InsertCommandType="StoredProcedure"> 
    <InsertParameters>
        <asp:Parameter Name="Nome" Type="String" />
        <asp:Parameter Name="NomeAbreviado" Type="String" />
        <asp:Parameter Name="Estado" Type="Int64" />
        <asp:Parameter Name="OrganismoID" Type="Int64" />
        <asp:Parameter Name="TipoCatalogoID" Type="Int64" />
    </InsertParameters>
</asp:SqlDataSource>

Code-Behind:

protected void Button2_Click(object sender, EventArgs e)
{
    SqlDataSource2.InsertParameters["Nome"].DefaultValue = TextBox13.Text;
    SqlDataSource2.InsertParameters["NomeAbreviado"].DefaultValue = TextBox14.Text;
    SqlDataSource2.InsertParameters["Estado"].DefaultValue = TextBox15.Text;
    SqlDataSource2.InsertParameters["OrganismoID"].DefaultValue = TextBox16.Text;
    SqlDataSource2.InsertParameters["TipoCatalogoID"].DefaultValue = TextBox17.Text;
    SqlDataSource2.Insert();
}

So What I want is that when the user clicks on Button2 it runs that stored procedure from the Database, however when testing it brings up an error message saying it could not find the stored procedure.

I am using the same connection string on another SQLDataSource and it works (this also uses a stored procedure which is in the same place as the one in the code above)

I realise this is grasping at straws - have you tried different syntax for calling your SP?

Here is a typical call that I use in a DataAccess class:

public int setUserTimescale(DataObjects.UserDetails myUserDetails)
{
    int ReturnValue = -1;
    SqlConnection myConnection = new SqlConnection(connectionString);
    SqlCommand myCommand = myConnection.CreateCommand();
    myCommand.CommandText = "User_Timescale_Up";
    myCommand.CommandTimeout = 120;
    myCommand.Connection = myConnection;
    myCommand.CommandType = CommandType.StoredProcedure;

    myCommand.Parameters.Add("UserID", SqlDbType.Int).Value = myUserDetails.UserID;
    myCommand.Parameters.Add("TimescaleID", SqlDbType.Int).Value = myUserDetails.TimescaleID;

    SqlParameter parameterReturnValue = new SqlParameter("@ReturnValue", SqlDbType.Int);
    parameterReturnValue.Direction = ParameterDirection.Output;
    myCommand.Parameters.Add(parameterReturnValue);

    try
    {
        myConnection.Open();
        myCommand.ExecuteNonQuery();

        // Get the return value
        ReturnValue = (int)myCommand.Parameters[2].Value;
    }
    catch (Exception e)
    {
        setDBError(myCommand, e.Message.ToString(), "User_Timescale_Up");
        ReturnValue = -2;
    }
    finally
    {
        myConnection.Close();
    }
    return ReturnValue;
}
