Permissions trouble transferring Access97 file to new computer

[John]

I'm not a database user, simply helping someone get started with a new
computer.

The old computer (win98se) runs a database in MS Access 97 pro, with
all the attendant permissions etc. I can work on the database without
problems, once I've opened the file with the requisite user name and
password.

I cancelled the password and exported the access file to a new
filename and then loaded a copy into the new computer (xp) running
another copy of office 97 pro.

I'm able to start the database file on the new computer but no longer
have access to any of the components - eg, if I select a table to
open, I get:

couldn't read definitions; no read definitions permission for table or
query 'the filename'

I've spent some time amongst the various help items on security and,
frankly, I'm bewildered by the whole thing and haven't the time to
study it at length.

It seems that the key is to work at 'administration' level but I can't
work out how to do that.

Could someone please direct me to some *simple* recipe for letting my
friend operate her database on the new computer?
