Cannot browse my nopcommerce1.2 after the installation.

Hello every one.
I have just down loaded nopcommerce1.2.
I zipped it build it and published it.And also made my IIS pointing root directory to the just published folder.
I am using .net3.5(VS2008,sql server 2005)
I have even executed the install sql scripts provided by the download.

But when i browse my local machine(http://localhost/one/Login.aspx) i am getting an error saying like 'System.IndexOutOfRangeException: CustomFormatting'.

Source Error:

Line 240:        public static string GetString(IDataReader rdr, string columnName)
Line 241:        {
Line 242:            int index = rdr.GetOrdinal(columnName);
Line 243:            if (rdr.IsDBNull(index))
Line 244:            {
