DT2 Pro won't open DT 1.n database

I’ve been using DT (personal) 1.9.16 for a long time, and then (thanks to MacUpdate) I just got a license for DT Pro 2.0. But I can’t get DT Pro 2 to open up my old DT Personal 1.n database. My old copy of DT 1.n can still open the database fine so it doesn’t seem to be corrupted.

Is there perhaps some confusion since I bought a new license instead of following the standard upgrade path?

Is there some way to convert old databases to the new format?

Help!

This post by Bill_DeVille should help.

Thanks! That looks like just what I needed.
