I could find older Pro 2 installers on NI website but noting available for Pro 3.
By adding Beatport and Beatsource link, NI had to change some things under the hood which broke the CMDR functionality inside 3.5.0.263 (and newer!) if I'm not mistaken. Therefor I need the very first version of 3.5.0 in order to use CMDR with Traktor Pro 3.
Recent public beta messed up my PC and I need to reinstall Windows. So that's the reason I'm reinstalling stuff.
Best,
