Hi all,

we created a new store and new store DB,

and after installing the POS client and configure the POS with the Retail Channel Configuration Utility

we got an error when trying to open the POS as shown here

I checked the event viewer and for this error

LSRetailPosis.POS.Program: System.NullReferenceException: Object reference not set to an instance of an object.
at Microsoft.Dynamics.Retail.Pos.DataManager.CustomerDataManager.ConvertToTransactionalCustomer(Customer axCustomer)
at LSRetailPosis.BusinessLogic.CustomerSystem.GetCustomerInfo(String customerId)
at Microsoft.Dynamics.Retail.Pos.Tax.TaxEngine.TaxEngineServiceProxy..ctor(IApplication application)
at Microsoft.Dynamics.Retail.Pos.TaxService.Tax.Initialize()
at Microsoft.Dynamics.Retail.Pos.SystemCore.Services.Initialize()
at Microsoft.Dynamics.Retail.Pos.SystemCore.PosApplication.Initialize().

can anyone help with this?
