@lectric77 > Just to confirm ... you first installed Traktor Pro 2, then installed Traktor 1 - DDJ-T1 edition? The good thing there is they are parallel installations. You don't need a TSI file for either version of the software in order for the DDJ-T1 to operate as it's already got that info loaded into the program trough the setup wizard. If it's not showing up within the wizard, you may have inadvertently done something that could have excluded it. Check the service center to ensure that you have the latest version of each:
Traktor 1 - DDJ-T1 Edition: v1.2.8
Traktor Pro 2: v2.0.3
