This article was originally written in 2014 and is most relevant for Liquid Rhythm 1.4.5 (and earlier), as well as early versions of Liquid Music. Liquid Music 1.8.0 + Liquid Rhythm 1.8.0 no longer suffer from the following (previously-common) issue (nor do Liquid Music 1.7.0 + Liquid Rhythm 1.7.0), though if this error is somehow ever encountered in later versions the recommended solution would be to perform a complete uninstall and then reinstall, as the error indicates a problem with configuration files for Liquid Rhythm / Liquid Music in Max for Live, which should be reset by a clean reinstall. Instructions here: macOS. Windows.
What may cause the error?
Running Liquid Rhythm in Ableton Live, through Max for Live, requires a special WaveDNA-specific configuration file for MaxMSP. This configuration file allows the Liquid Rhythm Max for Live device to find our installed application. When you install a new version of MaxMSP, it will overwrite these settings. Or if you install a new bit level of Ableton and Max for Live (ie, you were using Ableton 32-bit with Liquid Rhythm Clip mode, and then you installed Ableton 64-bit’s with Max for Live), it will overwrite these settings.
In those cases you might get the following error:

LRCA02-2: Configuration Error.

Solution
The solution is to get the configuration file back into the MaxMSP folder. There are two ways to resolve this issue:
- Easiest solution is to re-install Liquid Rhythm. On Windows you will need to uninstall and re-install. On Mac, you can re-run the Clip installer found in the .dmg file.
