Reply to Traktor Pro - Root directory problem! MacBook Pro OS X 10.6.2 Snow leopard

Hi

Can anyone please tell me how to change my root directory to default value? (Not using Preferences as I cannot open Traktor anymore)

This message comes up when I try and open Traktor Pro

Could not initialise Traktor with root directory set to ''G-DRIVE Mini:backupdb:Macbook Pro 15" 2010-01-05:Macintosh HD:Applications:Traktor." Reset root directory to default value!

Hit the ok button and this comes up.

Could not initialise Traktor. Logfile "Traktor.log" could not be accessed and is probably write protected.

Here is what I was doing just before I messed things up :-(

I had installed Traktor Pro on my MacBook Pro OS X 10.6.2 Snow leopard. I had a problem with the Mac and I needed to hand it in for repair. I saved all information on my time machine as advised. When I got the Mac back from Apple it had none of my info on it. I dragged the Traktor Pro from the saved file in the time machine and installed back on the Mac.

Traktor Pro launched and worked fine but I did not have any of my saved settings (Playlists and Midi controls). I believe I went to preferences and changed the root directory to (and this is where i messed things up!) the settings in the time machine folder (I believe I should have copied the setting over first from the time machine). Anyway, Traktor didn't like this and when I relaunched it it comes up with this message above....

I have deleted Traktor from my Mac completely (I believe) and downloaded it again. I did not plug the time machine at all through this process and when I tried to open it Traktor Pro comes up with the same message...

Any suggestions or help would be greatly appreciated!
