I'm surprised you've even got it to install on WinXP. Adobe no longer support PM6 at all. So you have to accept that there may be unresolvable incompatibilities between a product which would run on Win3.1 (1994?) and today's slick WinXP (2004?).
However, all is not lost.
There are about 10 computers hooked up to a network, but I'm not sure if that has anything to do with it.
I suspect it has everything to do with it.
By all means STORE all your files on a remote drive, but copy them ALL to a local drive for EDITING. By all, I mean all the linked files as well as the *.PMD file. Your error message "Error importing image into [file name], continue?" would be consistent with difficulty in linking to files on a remote drive.
Here's Adobe's advice from
Recommended workflow for creating PageMaker publications
5. Open publications from the hard disk.
Before you open a publication stored on removable media (for example, a Zip disk) or a network drive, copy it and all linked graphics files to your hard disk. Slow access times between the hard disk and removable or network disks, or multiple users working on a file at the same time on a network drive, can cause data to become incomplete, lost, or corrupt, resulting in damage to the publication.
The image files are JPEG, but I will try TIFF
TIFF is preferred format for print as there is no data loss when editing the image. If you are presented with JPGs and do not have to edit them at all, then you may be OK. If you need to crop or anything, convert to TIFF.
And always use File -> Place so that the correct import filters are used, though PM6's will be well out of date by now. Avoid Paste Special/Insert Object, e.g. WordArt. Create any effects in PhS or Illustrator or Corel, and save then as TIFF (bitmap) or EPS (vector).
switching to InDesign next year.
Great news, but why wait? Go for the discounted upgrade while it's still available.
