I am getting ready to import our historical orders from virtuemart into smith cart.   My research leads me to belive that there is no direct migration path, So I am looking at mannually moving over the data. 
	I am inserting the data into the following tables:
	DNN_Smith_Customer
	DNN_Smith_Invoicing
	DNN_Smith_PayHist
	DNN_Smith_StoreOrders
	DNN_Smith_StoreOrderDetails
	After the import  go into a users account and look at there orders and they are there but if I click on any of them I get the error: A critical error has occurred.An unexpected error has occurred.
	the log file reports:

	Am I missing a table that needs data?  Or is it that a value is incorrect?
