Trying to open an old database without success

Hi!

I have an old database which I don’t remember what version I created with. Now I want to open it with a V3 trial version without success. The log said it was skipped.

How are you trying to open the database?

Like this.

Any thought?

Does it work after restarting the computer? Or after creating a copy of the database in the Finder and trying to open the copy?
