"Live cannot access the undo history file and is switching to a memory based undo"

  • Live Versions: All
  • Operating System: All

In order to resolve this issue, please close Live and then trash the Undo folder (or Undo.cfg with Live 9) and the Preferences.cfg file. You will find these files in the following hidden folders:


\Users\[username]\AppData\Roaming\Ableton\Live x.x.x\Preferences\


/Users/[username]/Library/Preferences/Ableton/Live x.x.x/

Note: These folders are usually hidden by default. Here's how to access hidden folders.
