For some reason I am now receiving this same error message.  I don't do much payroll (I do mostly personal tax and corporate/ LLC tax returns).  I didn't receive this message when I filed the payroll tax returns right before the 5/1 deadline.  But, now as I have a client that normally takes care of their own payroll ask me to file something for them for 1st quarter, I received this message.  It's annoying that it still an issue on May 5th. it is also weird that I didn't get it earlier.
