I upgraded to Mojave, the Migration Assistant did not import DTPO. I downloaded a new copy of DTPO from your web site and entered my license. I opened my current database and the structure is there but the pdf data is grayed out and unusable. I have tried to register again and the register is grayed out.
I am also having trouble with Scan Snap
