I downloaded and installed Rekordbox v4.0.1 but I can't get it to work. Every time it crashes and displays the following message: "Unexpected application error". And the it opens the folder "C:\Users\User\AppData\Roaming\Pioneer\rekordbox\Crashes" and creates a .dmp file.
I still have Rekordbox 3.3.0 installed and its working correctly.
