Reply to Problem with DJTT Dicer Mapping for Traktor

I don't seem to be able get the DJTT Dicer mapping to work in Traktor Scratch Pro (1.2.7)

I've followed the steps to import the TSI file. Dicer then shows up in the drop down menus for Device, In-Port & Out-Port, but the Assignment Table is blank.

Any ideas? I'm sure I've probably missed out something simple.
