Thoughts? Have a beer. π
I honestly don't know but I would try to contact the CutList Plus author. I did a little searching and didn't find much useful info about CutList Plus Express. Is it really releated to CutList Plus?
I expect if you were able to get in touch with someone from CutList Plus (Bridgewood Design?) they might be able to take a look at the file exported from the plugin and see what is missing or what needs to be changed. If it's a change required to the plugin to make the export file usable, we'll have to find someone who can edit the file.
Out of curiosity, will CutList Plus Express accept a CSV file? If so, what happens when you import a CSV file from the plugin?
