Invalid Connection Information

[Linda]

I have many data access pages that worked just fine until
I had to reload XP. Now when I go into a page in design
mode I get an error 'Cannot find the database or some
database objects that this page refers to. Update the
connection information of the page, or fix the references
to the missing database objects.' I can get in and use my
tables, queries, forms and reports, just not pages. In
the page properties it will not allow me to build a
connection string. I am incredibly frustrated and would
appreciate any ideas.
