Multiple Payroll Data Files Error

SUGGESTED

I have a business that we always merge the payroll data files from 3 different locations to calculate the 941 amounts, do reports, etc. I have done this for almost 2 years with no problems. When I go to do it for this week I receive the error message "Error saving payroll data file". I get this same error in each of the 3 different businesses. Does any one have any idea on how to fix this issue? Thanks!
