@jtice1 Welcome to the forum!
You might try starting over with your unedited 1pux, and remove any embedded file attachments as described in this post.
Try the import again, and record the exact wording of the original error message (if any).
What error message did you get? Did it literally just say “error” and nothing else?
It sounds to me like you may have inadvertently corrupted the export.data file when editing it.
