When starting Traktor Pro 4, the application can crash immediately during the startup sequence and fail to open.  This can be caused by incorrect permissions within the __guest folders for Streaming/Beatport and Streaming/Beatsource.

Please follow these steps to reset the __guest folders:

1. Before launching Traktor, verify your network:

  • Make sure Internet/Wi-Fi is ON and you have a stable connection.
  • Ensure there are no access restrictions to Beatport/Beatsource services.

2. Try to launch Traktor.

  • It may crash during the first startup.
  • Once it crashes, make sure Traktor is completely closed.


Now, please navigate to the Beatport folder and Beatsource folder, depending on your operating system:
