After more then 10 years satisfied working with Traktor, I payed and downloaded to update my version Pro 3 to Pro 4.
All the settings from version 3 were duplicated to version 4 and everything works perfect, except the Kontrol F1. When I push a button to start a sample in the remixdeck, it will start but the sound is not always there. Sometimes it works sometimes it doesn't, it's not trustworthy and not usable for live gigs!
When I go back to Pro 3 with the same settings everythings works well!
I tried on many platforms to get a solution for this, can't reach a member of the support group, chat doesn't work, no mail adress available… what to do next?
