Traktor Pro 4.5.0: Numark Support Shadowed By Collection Wipe Bug

On April 22, 2026, Native Instruments released Traktor Pro 4.5.0. While the patch brings anticipated plug-and-play support for popular Numark controllers and streamlines streaming integrations, the launch has been severely marred by a critical deployment glitch.

Multiple working DJs have reported that Native Access—the software management hub for Native Instruments—is forcing the 4.5.0 update without user authorization. This silent update bug is generating a completely new, empty Root Folder upon launch, effectively erasing users' track collections.

The Silent Update Data Wipe Bug

For professional DJs, library management is paramount. The Traktor Root Folder houses the collection.nml file, which serves as the database for all track metadata, including saved hot cues, beat grids, and custom playlists built over years of performances.

Following the April 22, 2026 release, users on official Native Instruments forums reported that Native Access bypassed manual update preferences. Upon launching Traktor Pro 4.5.0, the software fails to migrate existing data and instead creates a blank Root Folder. This glitch presents a massive risk for professionals playing live gigs, as it instantly wipes out up to a decade of meticulous track preparation.

How to Protect and Restore Your Collection

If you have not yet opened Native Access since the April 22, 2026 update, take immediate preventative measures:

• Back Up Manually: Navigate to your Traktor Root Folder (typically located in Documents/Native Instruments/Traktor [Version]) and copy the collection.nml file, along with your Settings.tsi file, to an external drive or cloud storage.
• Restore from Backups: If you have already been affected by the silent update, you can restore your library. Right-click on the "Track Collection" node in the Traktor browser, select "Import another Collection," and navigate to the Backup/Collection folder within your Traktor directory to locate your most recent .nml backup.

New Hardware Integration: Numark Support

Beyond the deployment controversy, Traktor Pro 4.5.0 introduces official plug-and-play mappings for three popular Numark controllers:

• Party Mix II
• Party Mix Live
• DJ2GO2 Touch

These additions expand Traktor's accessibility for beginner DJs and professionals seeking ultra-portable backup controllers.

Under-the-Hood Changes: Beatsource and macOS 12

The 4.5.0 update also implements several structural shifts to keep pace with broader industry changes.

• Beatsource Integration Phased Out: Native Instruments has officially removed Beatsource integration components, including Previews and Free Trial buttons. This move prepares the software for the impending merger of the Beatsource streaming service into Beatport.
• macOS 12 Deprecation: Official support for macOS 12 (Monterey) has been dropped. Users must upgrade to macOS 13 (Ventura) or later to ensure compatibility and receive technical support.
• Stability Fixes: The patch addresses several critical startup crashes that affected earlier builds in early 2026.

While the feature additions in Traktor Pro 4.5.0 are welcome, the severity of the Native Access bug overshadows the release. DJs are strongly urged to secure their collection files before performing any software management tasks.
