I opened the PES file that I can't view through the PED-Basic software. Here is what I did: I installed inkscape (free) and the extension ink/stitch. You essentially have to save the new file as an older version (similar to saving a docx file to a doc so that older versions of software can read the document file). Newer files may not be compatible with the old PED-Basic. But makers are still putting out PES files. I experienced this same issue and found what worked for me. I picked up an old Brother PE-180D that uses the PED-Basic software.
