Erasing all MBP and reinstalling fresh Catalina

Hmmm I replaced all current folders in (DevonThink 3) with the old folders and I get this message. Also it unregistered me. I have access to all my previous databases and all but I get this message every time I start DT

Should I click “don’t ask me again” and “continue”? I clicked Cancel and restarted DT and restarted Mac but I still see the message. Wondering if I should click don’t ask me again and continue

‘Database “inbox.dtDatabase2” seems to be already in use!’
