Try reinstalling. I had that problem with a Prior year and just uninstalled and reinstalled and it worked. I am now having that problem with 2019! Check Uninstall all modules and States"

I"m having the same problem with QB but they said to do something different. I'm still working on getting that going again! What a pain! I called support for Lacerte and held for 2 hours!! I just don't have that kind of time....
