Trouble Upgrading from DTPersonal to DTPro

I trialled personal and then bought a licence to DTPro…

After installing I can never get it to run and get this message:

“The database you are trying to open seems to be either in use by another instance of DEVONthink Pro or has not been closed properly the last time it was used. Press ‘Continue’ to open the database anyway if you are sure it is not in use by another copy of DEVONthink Pro”.\

Whatever i do I can seem to sort it and it just hangs.

totally fed up with it, so would really appreciate some help


Try the following (clipped from the DEVONthink manual):

When you are upgrading from DEVONthink Personal to DEVONthink Professional,
the application will copy your existing DEVONthink Personal database to your
documents folder (’~/Documents/DEVONthink.dtBase2’) and modify all paths, URLs
and internal aliases accordingly if necessary.

If by any chance it doesn’t do this automatically, do the following: Copy the complete
folder ‘~/Library/Application Support/DEVONthink’ to your Desktop. Then, rename
it to ‘DEVONthink.dtBase2’ (mind upper/lower case). The folder icon should change
into a DEVONthink Pro database icon that you can double-click.
