PDF::Reuse - PDF from Word Doc

I am hoping this is the right group for my query, or just hope someone may
be able to shed some light on this.

I am using a script with PDF::Reuse that basically spits a header image and
pass protect into a PDF document.

My process is convert a word doc from ms office word into pdf and upload
that to the site ready for the perl script.

My problem is, that as soon as I add in a few extra rows in a table in the
original document, my perl page throws me the following error.

-------
Software error:
admin/newsletters/0.34543.pdf_1 can't be used as a form. Try e.g. to
save the file as postscript, and redistill---------I have tried many
different settings and techniques with no luck.

Has anyone who has used PDF::Reuse ever come across this or have any
suggestions to why this might be? I have spent hours on this to absolutely
no avail.

Thanks
