In any case, you should replace your current Melodyne installation with the newest version 4.2.3, which we have uploaded. You can find the installer in your user account. The good news according to Celemony is that the documents you have saved with the 4.2.2 version are not affected by the problem in any way. After installing the new version you can continue working as always.
