If you get this error, try the following:
- Quit DEVONthink
- In Finder select the menu Go->Go to Folder, copy and paste the line below and press Go
~/Library/Application Support/ABBYY/SDK - Drag the folder 12 to the trash
- Restart DEVONthink
We are waiting for a fix from ABBYY for this issue however the next update will include a workaround
