Database authentication failure after move

A few days ago I moved my protected Devonthink 2 Pro database to a new laptop, but I cannot acces it on the new laptop due to authentication failure. I have tried every combination of the username/password from the new laptop and the old laptop (they are different), but nothing seems to let me in. I have double-checked that I have Read & Write permission to the .dtBase2 file that I am trying to open.

Is there something else I’m missing? I no longer have access to the original database on the old laptop, so this is all I have to work with.

Thanks for your help!
