PPT created using Office 2000 has problems in PPT 2003

[nganapathy]

Create a PowerPoint Presentation with some macros using
Office 2000 and save the file.
Open the same file using Office 2003 PPT. And write a
macro using Office 2003 PowerPoint to make a copy of the
file created in older version (using PowerPoint 2000).
On running the macro , an error appears.The error message
is " Error Accessing File: Network connection lost". Its a
VB error.
On the analysis made I could see something called ODMA -
Open Document Management API, which Office supports only
for versions upto 2000.
Do u think the above problem is due to the OFFICE 2003 not
supporting ODMA ?. If not what could be the solution?.
