Python with DyBase

[Asem Eltaher]

Dear users,
I use Python version 2.4.3 and DyBase Object Oriented Database.  These 
are the first three lines in my program:

import os
import sys
import dybase

I usually get the error message:  ImportError: DLL load failed. Kindly 
be informed that I have in the folder: C:\Python24\Lib the following DLL 
files:
python23.dll
python24.dll
dybasedll.dll

Does soembody know what is wrong?
Thanks
Asem
