I have been using for years 2 PCs for DJing - both have Traktor pro and DasLight software active. However Sound is operated on one machine, light on the other. If one program crashes I can switch easily to the other PC. With the Nov. version Traktor pro does not work properly when DasLight is loaded. Although both processor and RAM have sufficient free load/space, the load indicator of Traktor pro is always in the red and the music playback is halting. System Win10, Intel i7.
