[Zope] ZODBCDA broken in Zope 2.5 - help

[vsbabu@vsbabu.org]

Hello,

   We've an old system using Zope 2.1.6 that uses ZODBCDA to 
   connect to an Access DB. We are in the process of upgrading
   Zope to 2.5.0. The latest ZODBCDA adaptor (on Win2K and Win98)
   gives broken product for this. The traceback is

Traceback (most recent call last):
  File "C:\ZOPE\lib\python\OFS\Application.py", line 531, in import_product
    product=__import__(pname, global_dict, global_dict, silly)
  File "D:\zopedata\Products\ZODBCDA\__init__.py", line 91, in ?
  File "D:\zopedata\Products\ZODBCDA\DA.py", line 92, in ?
  File "D:\zopedata\Products\ZODBCDA\db.py", line 86, in ?
ImportError: DLL load failed: A device attached to the system is not functioning.

I suspect it is because it can't find a file sql.dll. I couldn't find
this file anywhere either.

Does any one know a solution for this?

Many thanks in advance
