Traktor Pro - Playlist disappeared

Traktor Pro - Playlist disappeared

I was cleaning up my playlists in traktor,
and renamed one playlist with an underscore in the beginning.
Then it disappeared, does anyone know how to recover that playlist?
I am running Traktor on OS X.

Thanks

Problem solved, just needed to import a backup collection from the traktor folder in ~/Documents.

Help I have lost all my playlist. I have not opened Traktor for 6 months, (new son) I have lost over a year of work. :{ Can anyone help please.

Thanks

Did you try this? ^

My problem is a little more serious, when I open TRAKTOR I get this error: Traktor:Traktor.exe-Entry Point Not Found. (Red X) The procedure entry point NtAlpcSendWaitReceivePort could not be located in the dynamic link library ntdll.dll.

What version of Traktor? Is it a cracked copy?

Its a registered copy 1.2.6
