Provide as much detail of the issue here:

Now when I open it, it does the following

   1) throws an error in syslog about "unsupported URL"

   2) when I switch on a CDJ2000 and throws a second error in syslog advising PSvLinkSysMgr crashed and dumped a trace in ~/Library/Logs/DiagnosticReports/PSvLinkSysMgr...

   2a) when this happens, rekordbox needs a SIGKILL (kill -9) to quit

   3) if I leave the CDJ2000s off and try to export soemthing to USB, it also locks up

   3a) this also requires a SIGKILL to quit

Here's the initial error that shows up in syslog:

[0x0-0x46046].com.pioneer.rekordbox[783]: Error Domain=NSURLErrorDomain Code=-1002 "unsupported URL" UserInfo=0x227e8a0 {NSErrorFailingURLStringKey=, NSErrorFailingURLKey=, NSLocalizedDescription=unsupported URL, NSUnderlyingError=0x227e7b0 "unsupported URL"}

Here's the second syslog error when PSvLinkSysMgr crashes:

com.apple.launchd.peruser.501124: Job appears to have crashed: Trace/BPT trap: 5

The crash file's attached.

Appreciate your help!!
