Hi Lee, first of all welcome to the forums.
Moved this one to the correct forum. I am no expert on Traktor, so I hope one of our other readers can help you with this one.
Word of caution (for everyone).
If you are going to use a new tool, or updated version of a tool with new features, try it out with a small test collection before committing your master collection to it. And ALWAYS make sure you have a backup of your actual setup (=music, analysis files, settings, etc.) before running the new software. That way you can always go back to the situation you had BEFORE trying the new tool should something go wrong as it seems to have done in this case.
