The rekordbox [LINK] button does not show up when I connect my computer to the CDJ/XDJ with a LAN cable.

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

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:
- rekordbox program file
- ProDJ Link System Manager
- ProDJ Link NFS Server
- edb_streamd
check "Windows Firewall settings"
PRO DJ LINK may fail to run properly if your computer is connected to multiple networks as the networks (wired LAN, wireless, etc.) may interfere with each other. If this is the case with your computer, you can resolve the issue by disabling networks not used by PRO DJ LINK or set the network precedence properly to favor the network used.
PRO DJ LINK may fail to run properly if the Port used by rekordbox for PRO DJ LINK is being used by another application (NSF server, etc.). To resolve this issue, close the application or service being used and then try again.
PRO DJ LINK may fail to run properly if Internet Sharing is enabled. If this is the case, disable Internet Sharing and then try again.
When there is a router connected on the network used by PRO DJ LINK, the network may fail to be established properly depending on the order in which connected devices are powered on. Either first turn on the power to the router and then connect the device, or disconnect the router.

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.)

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.
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:
- rekordbox program file
- ProDJ Link System Manager
- ProDJ Link NFS Server
- edb_streamd
check "Windows Firewall settings"
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.
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.
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.

Files which I imported from my USB device previously now display “File is Missing,” and cannot be played.

When a track has been imported from an external device, rekordbox may not find the track if the device’s drive letter (“E:” for example) differs from the drive letter at the time the track was imported. Change the drive letter so it is the same as when the track was imported.
With iTunes, if the “Keep iTunes Media folder organized” setting was enabled, when titles or other types of track information is changed in iTunes, iTunes changes the track’s location, file name, etc. To import the same tracks on iTunes and rekordbox, disable the “Keep iTunes Media folder organized” setting.
