| Problem | Most Likely Fix | | :--- | :--- | | "Invalid ARL" error | Your ARL expired. Deezer ARLs expire after a few months or if you log out of all devices. Extract a fresh ARL. | | HiFi option greyed out | Your ARL is from a Free or Premium account (not HiFi). Upgrade your Deezer subscription. | | Downloads stuck at 0% | Deezer changed their API endpoint. Update Deemix to the latest version (check Gitlab for new releases). | | FLAC downloads are 320kbps | You have a Premium account, not HiFi. Check your Deezer billing page. | | "Track not available in your country" | Deezer geo-restricts some content. Use a VPN set to the track’s allowed country before extracting the ARL. | | Deemix won't open | Python dependency conflict. Use the standalone GUI version instead of the pip-installed version. | If you’ve spent any time in online music
