Okay here is the official working answer (and yes it worked). The error (in my case) 601ERRV:4 "Invalid Primary Date of Birth" meant... That I hadn't entered the date of incorporation in one particular spot (which happened to be in the beginning questions). Even though when you looked at the "forms" that date was already there in multiple places, it still needed to be entered again.
Thanks for everyone who worked on this. DP
