Error message when distilling Pagemaker 7.0 document

[HBYardSale]

I wonder if anyone can tell me what is causing these error messages (below)
when converting PS files to PDF. They appear in every Pagemaker 7.0 document I
convert to PS. All documents have Word files I have placed and the text is
always the same -- Times Roman Regular and Arial Bold.

It's not hindering my work because I have checked the appropriate box that
let's the process continue. But I'd still like to know what the error means.

Also, when is says "not found". Not found where?

Any help understanding how this program works would be very much appreciated.

Thanks!!
