Accessing Database design mode

There is an DB that was create well before my time at my job and I have very
little experience with Access and need some help here.

Access 2003, XP SP3.

The first issue:
I need to get into the Form Design page of this particular DB the 2 ways i
know how to get into the Form Design or any other design mode is
1) have the DB open and on the main page of the DB you can right click on an
open space and than choose Form Design and go about doing what you need to
do. However I can not do that in this one particular DB -- i right click in
an open area on the main page and nothing happens.

2 i minimize the main page of the one that i can get into the design mode i
can see the database design box that has the Objects (tables, queries, forms,
etc) on the left side and on the right side is where you can choose the forms
(frm_Reports, fr,_SelectDocument, etc.) but on the one that i can not right
click this box is not present and i can not get into the design mode.

3) if i click on Tools and database utilities and than click on Switchboard
Manager, i get a message saying that "The Switchboard Manager was unable to
find a valid switchboard in this database. Would you like to create one?"
Of course I don't want to mess anything up, especailly since the DB is
working for the people that go into it everyday. There are 2 users that only
need to go into it once in a while to do a search and when they do, they get

" ' \\....\....mdb' is not valid path. Make sure that the path name is
spelled correctly and that you are connected to the server on which the file
resides.

OK"

Any help would be greatly appreciated.

Thanks,
