2012 SP 4, can't drag Spline points?

I just upgraded from 2011 today and after working for a couple minutes I came about a spline with two end points and no other spline points.  I can no longer drag the two end points of the spline as I could in 2011.  I get the error "This drag created invalid geometry.  The pre-drag sketch state will be restored."  Any way to use splines again or save my file so that I can open it back up in 2011?

Thanks
