I had downloaded the trial of DTPO, but ultimately decided that the DTP fit my needs better. How can I take DTPO off my system and install DTP without disturbing my existing databases?
Delete the application and you should be fine.
You might also want to delete the folder ~/Library/Application Support/DEVONthink Pro 2/Abbyy. The Abbyy folder is the OCR stuff and takes up about 250MB of space.
Thx for the assist, Greg. Good call. 8^)
