[Dxbase] Can't open other mdb's

[George Harlem W1EBI]

In DXbase 2004 I had my main log as W1EBI.mdb and two other
databases--trial.mdb that I used for testing, and LoTW.mdb that I used
for, obviously, LoTW adif's.  I created DXbase 2005 and imported all
three of those databases from 2004.  The W1EBI.mdb opens fine, no
problem.  I just downloaded my entire LoTW adif into LoTW.mdb in DXbase
2005, but when I opened DXbase--it opens with my mail log database--and
went to the File pulldown and selected "New database", then tried to
open LoTW.mdb, I'm told the program is unable to create a new database.
Obviously I now realize that pulldown is to CREATE a new mdb, not to
open another one.  Since I have (foolishly!) checked the box on the
opening screen that will no longer give me the option of which database
to open, how do I now get into the other existing mdb's?
