It worked fine like that for me to ---------------- until today.  Sometimes I really hate updates

I went back to the MN return I finished a few days ago and sure enough, it now has the exact error IRonMan described.  Fortunately, I filed that return and it was accepted by MN.

The update did not cause an error on the MN Property Tax Refund return.  However, I tried to file it after the update and it is still rejecting with same error saying the version is out of date.
