If you are receiving the error "Mixdown aborted - Can't save." Then there are a few things to look for. First, illegal characters such as question marks, slashes, asterisks, etc.. Also excessively long file names can also cause this issue. Try to keep the names under 11 characters for a Data CD.

In Audio Creator or Vinyl Recorder, try saving or exporting again once you rename the markers. Every marker must have a different name.
