dashCommerce

This is really strange, a fresh download and when ever I add something to the cart I get the following error

Message="Invalid cast from 'System.String' to 'System.Guid'."
  Source="mscorlib"
  StackTrace:
       at System.Convert.DefaultToType(IConvertible value, Type targetType, IFormatProvider provider)
       at System.String.System.IConvertible.ToType(Type type, IFormatProvider provider)

       at SubSonic.ActiveRecord`1.Save(String userName)
       at MettleSystems.dashCommerce.Store.OrderController.ResetShippingAndTaxAndDiscount(Int32 orderId, String userName) in

Is there a patch I am missing? Any help would be greatly appreciated!

I ran the upgrade script for the SQL database from the release candidate to the release version. (Not sure if this has anything to do with the error)

 Thanks

Are you using the 3.0.1 release? If so, then you probably missed an upgrade script as the sequence was:

RC -> 3.0 -> 3.0.1

Legend!

Thanks :) That seems to have fixed it

 Excuse me,

Which script did you use to resolve the error?. 

 Please let me know... thank's .
