I just spent 1.75 hours on the phone with Lacerte support. They indicated that the problem is caused by either using borders or inserting gif files into the letters. We don't do either. They indicated that they consider the problem to be on my end even though I can still print 2019 organizers from the 2018 software. I asked them to check the community posts since this appears to be a wide-spread problem from what I see. They at least "escalated" this to a "level 3" and promised to call me back. Heavy sigh!
