Could you detail what does happen, when you try to open your Foxpro
DBF files on the failing stations? (any error message?).
As you mentioned "uDirect Professional", can you specify if your
problem occurs with uDirect (directly from within InDesign), or from
uPlan? Or both?
BTW, your version is now quite (very) old.
I just read the Release Notes for 4.0.4, 4.5.2 and 4.6.2, but could
not find anything related to DBF files.
I would however try an upgrade to 4.6.2 (using CS2, and not being able
to upgrade to CS3 or CS4, is the only thing which would prevent you
from upgrading to XMPie 4.6.2).
If you are using linear barcode, do not forget to also upgrade your
XMPie barcode fonts (as a new batch was released with 4.6).
While you can download uDirect directly from the
www.xmpie.com website
(Download Center:
http://www.xmpie.com/?id=1274), you will need to
contact your Xerox or XMPie representative to get a copy of uDirect
Professional (uPlan).
