A v8 Paradox table should work fine. ChurchPro probably specified a
version
to make sure you weren't using DOS level Paradox tables. Just in case
Access is getting confused, try calling the file something other than MAIN
(example, "church.db"), and try saving it to the C: drive instead of the
desktop.
As far as I know, only the Professional version and Student/Teacher
versions
of WP Office come with Paradox. You said it is a free demo, but I don't
think they have a free demo for the Pro version. You might have the
Standard version which does not include Paradox.
