Adding, merging and saving PDF's
I'm trailing to Adobe products before purchasing.
I'm trying to take several PDF documents to merge into one. I have successfully done so with some, but PDF's created from within publisher is giving me issues. Every time I try to add these to my already merged document, it says that the file already contains a container. I have no idea what this means and how to fix it. I have tried googling to answer, and even though I have seen many responses, it doesn't seem to fit my issue, or I'm not understanding all the technical terminology.
I only have 2 days left of the trail, so want to make sure this works before spending a fortune purchasing this product.
Please someone help me in plain, easy to understand English - without too much technical jargon please.
Thanks
