Using the Tidal app for Mac OS
Tidal worked great with version 1 of Jaksta Music Miner.
Tidal seems not to be working with v.2 Jaksta Music Miner
Is testing downloading with the unlicensed version of version 2 Jaksta Music Recorder
Is version 1 still available for download? Could it work better?
When was the last time that you were able to successfully download a stream from Tidal using the previous version of Jaksta? V1 and V2 of Jaksta Music Miner/Recorder operate in almost the same way, so there should be no reason that the earlier one worked and the new one doesn't. It is possible that Tidal has changed something with their streaming process in the meantime and that is causing the issue.
What would be good is if you could try and download a couple of files from Tidal and then when they fail you can send us the log file. You can find it in Music recorder by going to Preferences > General > Find Log File.
Don't forget that you can use Audio Capture mode in V2 of Music Recorder as a workaround for streams that can't be downloaded.
