Last updated:


If you get this message when loading up a Spitfire instrument, please follow the steps below.

This error means that the instrument cannot locate the samples it needs to work. 


If you have moved the samples to a new location on your computer then you can resolve the situation as follows:

1. Close your DAW

2. Launch the Spitfire Audio App and log in

3. Find the instrument in question by searching in the top right hand corner

4. Click on the instrument artwork

5. Click Repair in the bottom right, and by following the instructions on screen select the location of the library

6. A small download will begin, be sure to wait until this is complete before proceeding

7. Once the download is finished, launch your DAW again and reopen the instrument


If one of your instruments is missing from the samples folder, you can reinstall as follows:

1. Close your DAW

2. Delete the offending LABS from the Presets and Patches folder

3. Launch the Spitfire Audio App and log in

4. Find the instrument in question by searching in the top right hand corner

5. Click on the instrument artwork

6. Click the "cog" in the bottom right and choose reset

7. Click install

8. Choose the location you wish to store the sample content for the instrument

    I am having this issue with Eric Whitacre Choir (which I installed from an SA hard drive). I followed the repair instructions, the download commences, the install indicates success, but the problem persists. Suggestions?

    Hello, I've exactly the same problem as Garry with the Eric Whitacre Choir. Installed from SA hard drive and succesfully located in the Spitfire Audio app but still get the error #4 message when I open the plugin in my DAW. Thanks

    Hi, I'm having this problem with all of my LABS instruments unfortunately. Are you able to help? Thanks.

    Paul, I was having the same problem. Here's the fix that worked for me:
    Manually delete the contents of your 'Spitfire - LABS' folder. Then, go to the Spitfire app, and there is a small cog symbol next to each instrument. Go to that, and click 'reset'. Do this for each individual instrument, and redownload them.
    This surprisingly fixed the issue for me entirely. I can now use all LABS instruments without any issue.
    NB: If it doesn't work perfectly the first time (but it probably will), just do the same method again.
