Sorry to hear you're having trouble with Puff Puff MixPass not passing audio.
An internet connection is required only for the initial activation of the software. Once your plugin is activated, it will function without the need for internet access. Our software's license files are tied to your system ID, but occasionally, changes in hardware or operating system updates can alter this ID and invalidate the license.

We're working on solutions to handle this automatically in the future if an internet connection is available. For now, you'll need to manually delete the license file and activate the software again.
Check out this guide in our FAQ for details:

Can you confirm if a system or OS update is the culprit in this situation? Also, as an end user that has experienced this situation, do you have any suggestions on how we can make this easier to deal with in the future? Maybe a popup explaining the situation? We're always trying to make things better.
