Hi,
please make a tech support ticket via your my.presonus.com account, to let us know what you mean by "not working correctly" and we can work with you to resolve. We have those instruments working fine here in playback and note entry with the drumpad. There was an issue in the past with claves in playback crashing the score - you need to remove the claves sound in the Sounds dialog, and download it again to fix that. But otherwise, we're not aware of an issue.
