Reply to Beginner: APC40 Mappings for Traktor not working!

Hi guys

I am completly new to Djing.
After reading a lot in this community I decided to buy the APC40 and start using it with a mapping for traktor and then later getting into ableton.

I am facing now the problem that no matter what .tis I load into the Traktor the mappings don't really work.

The most basic buttons - usally play, cues, etc work but filters don't.

Am I not getting what it is about or do I have version problems?

I have the traktor scratch pro version 2.1.2 on a 10.7.3 Mac.

Haven't made any update on the APC40!

Thank you for any advice or help!
