I'm not sure if the full charactermancer code is available And even if that version is complete, it's possible the code/compendium data differs enough from the current version of the sheet that the old DD5thEditionLegacy code is too outdated to work. But it's possible you might have forgotten having the 5E Compendium active in your test game? Charactermancers must have a compendium to work at all. Think the Shadowrun 5e sheet has a character sheet importer that uses the charctermancer, and the quirk is that you need to have any compendium in the game for it to open, even if it doesn't use any info from them.
