copypdffile not working.

I received an old Word macro that splits a large pdf file in several pdf documents usig the copypdffile method in VBA.

It was writen for an old pdfCreator version and with the new versions (1.7.1 - 1.7.2) doesn't work.

The problem starts in the following sentence:

Set pdfforgePDF = CreateObject("pdfforge.pdf.PDF") 

Here I get the error, looking in the COM help document, it seems to be right, but I get the error -2146232576 ( Automation Error).

What am I doing wrong?.

Thanks in advance.

Antonio.
