Update: The master developer removed the payroll record from SY_Module and was able to get data conversion to run on the rest of the system. So, the customer is up EXCEPT for payroll. The MD suggested that I reinstall payroll, but the installer thinks that payroll is already installed. If I choose Reinstall from the menu, I will then need to reinstall the product update, which may put me back to the original problem. I don't know what to do. Help! Anybody?
