Steps to fix Ableton Live corrupt files

Solution 1 – Re-trigger the file recovery process

In some cases, it might be possible to restore a temporary copy of the Project file in one of Ableton Live’s crash report folders. The temporary file is usually an older version of your set that was successfully saved.

Important note: If you want to recover your corrupted files, the recovery must be done with the same version of Ableton Live which created the save, and also the same Windows platform.

To re-trigger the file recovery process, please follow these instructions :

  1. Go to the following location, which is normally a hidden folder – C:Users[Username]AppDataRoamingAbletonLive x.x.xPreferencesCrash. If you need information regarding how to see hidden folders on your PC, go to Ableton’s support page.
  2. In the Crash folder, the files and folders will have the date and time of the crash in their names :
  • “2018_12_12__16_02_35_BaseFiles” (this is a folder)
  • “2018_12_12__16_02_35_Crash.als”
  • “2018_12_12__16_02_35_CrashRecoveryInfo.cfg”
  • “2018_12_12__16_02_35_Undo” (this is a folder)
  1. Remove the dates from the file names. After doing so, they will look like this :
  • Basefiles
  • Undo
  • CrashRecoveryInfo.cfg

Note: Crash.als does not need to be renamed and can be left in the same folder

  1. Drag the 3 files mentioned above into the source Preferences folder and replace the correspondent files
  2. Now you can start Ableton Live. The file recovery process should be reactivated.

Solution 2 – Switch to Adobe Audition
