I cannot play back audio tracks from rekordbox on the DJ player via a link connection.

PRO DJ LINK works when rekordbox is in EXPORT mode. (It does not work in PERFORMANCE mode.)

1. If the [UNLOCK/LOCK] option on the DJ Player is set to [LOCK], you will not be able to load tracks to the DJ Player while a song is playing (for the CDJ-2000 only). You will also not be able to drag tracks if you load them at the same exact time as a Cue is being called up on the DJ Player.

2. Depending on the security software used on your computer and its operating system settings, it may not be possible to establish a PRO DJ LINK connection. If this occurs, it will be necessary to check your settings for the following four programs to ensure that they are not blocked:

3. For Mac OS X, note that music files with long file paths cannot be played back using PRO DJ LINK. Make sure to save music files to a save location with a file path no longer than 256 characters.

4. Music files transferred from Windows XP to Windows Vista/7/8 and saved to My Music may become unable to be played back using PRO DJ LINK. If this appears to be the case with your files, rename the folder where the music files are saved and then use Relocate to reassign the location once the "Media is Missing" message pops up to reset it.

5. Note that [Device] song tracks cannot be loaded onto the CDJ using PRO DJ LINK. To play such song tracks, connect the device directly to the DJ Player instead.
