[AccessD] Importing (or linking to) Paradox files

My client sent me an email 3 weeks ago with three Paradox .db files
attached.  I was able to successfully link to 2 of those 3 files, but the
third says "file not the expected format".  The client just sent me 60 of
these files which I need to import into Access.  ALL of them now say "not
the expected format", including the same file names of the two that
previously imported.

My question is are there versions of paradox files that Access can
understand these but not those?  Are there various drivers that need to be
downloaded or something?

The client says that he installed a SP for Paradox 11 in the last 3 weeks.
Could that have screwed around with the files and made them into a format
that Access no longer understands?  To make things even Murkier, he claims
that he can open them just fine there.

Hmmmm.
